Technical Field

The invention relates to the technical field of medical instruments, in particular to an electric coagulation hook for a single-hole thoracoscope minimally invasive surgery.

Background

The single-hole thoracoscopic surgery is the international leading-edge minimally invasive technology, and surgical instruments and equipment enter an abdominal cavity through micropores in the surgery, so that the technology is quick, small in damage and free of scars. The single-hole thoracoscope technology is that after four holes, three holes and two holes are changed into one hole in the traditional thoracoscope operation, the angle is changed into zero, and new challenges are provided for the main scalpel doctor in experience and skill.

The electrocoagulation hook is usually used in a thoracoscope operation process, mainly plays a role in poking and separating internal organs of a human body and performing electrocoagulation hemostasis on bleeding organs in the human body, has good operation stability, high safety and strong practicability in the operation process, and can well meet and achieve the expected purposes and purposes of medical staff. Referring to fig. 1, there is shown a prior art electrocoagulation hook for thoracoscopic surgery, which comprises a hook head 10 and a hook body 20 connected with the hook head, wherein the hook head 10 is designed as a right-angled hook. However, the electrocoagulation hook of the design is used in the single-hole thoracoscopic minimally invasive surgery and has the following problems:

1. in the single-hole thoracoscope operation process, after the electrocoagulation hook extends into the thoracic cavity from a single hole, the movable angle of the electrocoagulation hook is almost zero, the position of the hook head 10 can only be observed along the direction of the hook body 20, but the hook head 10 has smaller volume, so that the exact position of the hook head 10 cannot be judged because the hook head 10 is shielded by the hook body 20 when observed along the direction of the hook body 20, the non-operation part in the operation can be injured in the operation process, unnecessary pain is brought to a patient, and the safety performance of the electrocoagulation hook is reduced;

2. the main working part of the electrocoagulation hook is the hook tip 11 of the hook head 10, but in the operation process, when the electrocoagulation hook is adjusted, the bending section 12 of the hook head 10 is easy to touch the non-operation part, and the non-operation part is easy to hurt due to high temperature generated after the electrocoagulation hook is electrified, particularly the blood vessel is greatly influenced, and the success rate of the operation is even influenced.

Disclosure of Invention

The technical problems to be solved by the invention are as follows: aiming at the defects of the prior art, the electrocoagulation hook for the minimally invasive surgery of the single-hole thoracoscope is provided, the electrocoagulation hook can conveniently judge the accurate position of the hook head, and the bending section of the hook head of the electrocoagulation hook can not hurt the non-surgical part when the electrocoagulation hook is adjusted.

The technical problem solved by the invention can be realized by adopting the following technical scheme:

the utility model provides a haplopore thoracoscope is electrocoagulation hook for minimal access surgery, is in including coupler body and setting the gib head of coupler body one end, the root section of gib head is along the perpendicular to the direction perk of coupler body axis makes the axis of this root section with the axis of coupler body forms an contained angle, just the gib head most leading edge with shortest distance between the axis of coupler body is greater than half of the biggest external diameter section of coupler body.

In a preferred embodiment of the invention, the hook head is a right-angle hook, and a heat insulation layer is coated on the bent section of the hook head.

In a preferred embodiment of the invention, the included angle is 45 °.

In a preferred embodiment of the present invention, the thermal insulation layer is a silicate composite thermal insulation coating layer.

In a preferred embodiment of the invention, the electric energy converter is arranged at the other end of the hook body; a conductive rod is arranged in the hook body, one end of the conductive rod is connected with the hook head, and the other end of the conductive rod is connected with the electric energy converter; the outer layers of the hook body and the electric energy converter are coated with an insulating layer; the electric energy converter is internally provided with a power socket matched with a power supply, and the power socket is a cylindrical metal column which extends out of the electric energy converter from the inside of the electric energy converter.

Due to the adoption of the technical scheme, the invention has the beneficial effects that: the root of the hook head is tilted, so that the hook head and the hook body are not on the same plane, and the hook head tilted outwards can be observed along the direction of the hook body in the operation process, so that the accurate position of the hook head can be accurately judged, and the possibility of injuring non-operation parts in the operation process is reduced. The hook head is characterized in that the bent section of the hook head is coated with the heat insulation layer, the heat insulation layer effectively isolates the high temperature of the bent section of the hook head from diffusing outwards, and when the position of the hook head needs to be adjusted, even if the bent section of the hook head touches a non-operative part carelessly, the non-operative part cannot be injured due to the high temperature.
