Technical Field

The invention relates to the technical field of medical instruments, in particular to laparoscopic surgical instruments.

Background

The traditional method of the posterior laparoscopic surgery is to make three small incisions of 1 cm in the waist of a patient, each of the small incisions is inserted into pipeline-shaped working channels called trocar, then cutting operation is carried out through the three pipelines, and special lengthened surgical instruments are used for completing the same steps as the open surgery under television monitoring, thereby achieving the same surgical effect.

Laparoscope is similar to electronic gastroscope, and is medical equipment with a miniature camera, and laparoscopic surgery is surgery performed by using laparoscope and related equipment.

Because the currently used pipelines can only pass in and out hand-operated surgical instruments at the same time, laparoscopic surgeries can be completed by establishing a plurality of puncture holes on the abdominal wall of a patient, so that a plurality of puncture hole-puncturing scars and scars of incisions for taking samples are left on the abdominal wall of the patient, a plurality of scars are left on the patient, and the recovery of the patient is not facilitated.

Disclosure of Invention

The invention mainly aims to solve the problem that the existing pipeline can only pass in and out surgical operation instruments at the same time, so that laparoscopic surgery can be completed only by establishing a plurality of puncture holes on the abdominal wall of a patient, and a plurality of puncture hole scars and specimen taking incision scars are left on the abdominal wall of the patient, so that a plurality of scars can be left on the patient, the recovery problem of the patient is not facilitated, laparoscopic surgery instruments which can perform laparoscopic surgery only by opening incisions on the abdominal wall of the patient, cannot leave a plurality of scars on the patient, and are beneficial to the recovery of the patient are provided.

The object of the invention is mainly achieved by the following scheme that laparoscopic surgical instruments comprise a connecting sleeve, a sealing sleeve and an elastic sleeve, wherein a plurality of finger sleeves are arranged on the connecting sleeve, a guide channel is arranged at the end of each finger sleeve far away from the connecting sleeve, a connecting ring is arranged at the end of each connecting sleeve far away from the finger sleeves, each sealing sleeve comprises a sealing shell and a connecting pipe with an operation hole, an external thread layer is arranged at the end of each connecting pipe, an internal thread layer matched with the connecting pipe is arranged on the sealing shell, an internal thread layer in threaded connection with the external thread layer is arranged on the top end side wall of each sealing groove, a sealing inclined plane for clamping the finger sleeves is arranged at the side of the connecting pipe far away from the internal thread layer, an intra-abdominal cavity elastic ring is arranged at the 363 end of the elastic sleeve, a lower elastic ring and an upper elastic ring are arranged at the end of the elastic sleeve, the lower elastic ring and the upper elastic ring fit ring, a plurality of the lower elastic ring and the upper elastic ring are clamped on the connecting sleeve by the connecting sleeve which is matched with the connecting pipe, a plurality of the connecting sleeve is arranged on the connecting sleeve, a guide channel which is arranged between the elastic sleeve, a connecting pipe, a needle sleeve, a needle ring is arranged at the connecting pipe, a needle sleeve, a needle ring which is arranged at the upper end of the elastic sleeve, a needle sleeve is arranged in the needle sleeve, a needle sleeve is arranged in the needle sleeve, a needle sleeve is arranged on the needle sleeve, a needle sleeve is arranged on the needle sleeve, a needle sleeve is arranged on the needle sleeve, a needle sleeve is arranged on the needle sleeve, a needle sleeve is arranged on the needle.

Preferably, the lower elastic ring and the upper elastic ring are provided with limiting bulges matched with the connecting ring. The lower elastic ring and the upper elastic ring are provided with limiting bulges matched with the connecting ring, and the connecting stability between the connecting ring and the lower elastic ring and between the connecting ring and the upper elastic ring can be improved due to the arrangement of the limiting bulges.

Preferably, the number of the finger sleeves is at least three, operation is convenient to use different operating instruments, and the applicability is .

Preferably, the number of the finger sleeves is 4, instruments needed for laparoscopic surgery are 3-4, and the arrangement of the number of the finger sleeves is high in practicability.

Preferably, the connecting sleeve and the finger stall are formed by bodies, and the connecting sleeve and the finger stall are formed by bodies, so that the air tightness of the connecting sleeve is improved.

Preferably, the connecting ring, the intra-abdominal cavity elastic ring, the upper elastic ring and the lower elastic ring are all made of silica gel materials. The connecting ring, the intra-abdominal elastic ring, the upper elastic ring and the lower elastic ring are all made of silica gel materials, so that the elasticity is good, and the operation is convenient.

Preferably, the axial length of the elastic sleeve is 3-6 cm. The axial length of the elastic sleeve is 3-6cm, and can be selected according to different abdominal cavity wall thicknesses of patients.

Preferably, the end of the sealing inclined plane close to the inner threaded layer is provided with an elastic cushion, and the end of the sealing inclined plane close to the inner threaded layer is provided with an elastic cushion, so that the elastic cushion can better clamp the finger sleeve wall.

Preferably, a windshield made of a flexible material is arranged in the operation hole, the end of the windshield is connected to the end of the operation hole, which is far away from the connecting sleeve, a support ring is arranged on the side wall of the operation hole, which corresponds to the end, close to the connecting sleeve , of the windshield, and a wind shielding gap is formed between the windshield and the side wall of the operation hole.

Therefore, the laparoscopic surgical instruments have the advantages of simple operation and strong practicability, can perform laparoscopic surgery only by making incisions on the abdomen of a patient, do not leave more scars on the patient, are favorable for the recovery of the patient, have good air tightness during the surgery, and are favorable for the smooth operation of the surgery.
