Detailed Description

The transmission structure of the circumcision device of the present invention will be further explained with reference to fig. 1 to 5.

A transmission structure of a circumcision surgical instrument is characterized in that: comprises a working assembly 1 and a transmission handle 2. The working assembly 1 comprises a housing 11, an annular push rod 13 disposed in the housing 11 and capable of moving along the axial direction of the housing 11, an annular blade 16 mounted on the upper end of the annular push rod 13, a nail bin 12 sleeved outside the annular blade 16, a tortoise head cover 15 located on the upper end of the housing 11, a nail plate 152 fixed on the annular folding edge of the tortoise head cover 15, and a gun core 14 for positioning the tortoise head cover 15. The matching structure among the housing 11, the annular push rod 13, the annular blade 16, the nail bin 12, the glans penis sleeve 15 and the nail plate 152 is the prior art, and the detailed description of the embodiment is omitted. The side position of the lower end of the shell 11 is provided with a hook groove 17, and the hook groove 17 is of an upper opening structure. Have on the upper end side of transmission handle 2 and to cooperate the round pin axle 21 to the hook groove 17 in, transmission handle 2 rotates through round pin axle 21 and connects on the lower extreme position of shell 11, and the lower extreme of the upper end of transmission handle 2 towards annular push rod 13 rotates the back, and the lower extreme of annular push rod 13 is extruded to the upper end of transmission handle 2 to promote annular push rod 13 and remove towards tortoise head cover 15.

Specifically, as shown in fig. 4, a U-shaped seat 23 is formed or bolted on the side surface of the upper end of the driving handle 2, and the pin 21 is fixed on the U-shaped seat.

A cross beam 111 is formed at the lower port of the housing 11, and a central hole 1111 is formed at the central position of the cross beam 111. The gun core 14 can be axially limited and circumferentially matched in a central hole 1111 of the cross beam 111 in a rotating manner, the lower end of the gun core 14 extends to the outside of the shell 11, namely the lower part of the cross beam, the upper end of the gun core 14 is in threaded transmission fit with a lower end guide part 151 of the glans penis sleeve 15, and the gun core 14 can be rotated to drive the glans penis sleeve 15 to move up and down relative to the shell. The transmission handle 2 is a hollow tubular structure, so that the lower end part of the gun core 14 is accommodated at the upper end of the transmission handle 2 after the upper end of the transmission handle rotates towards the lower end of the annular push rod 13, and the cross beam avoiding groove 21 is formed in the upper end position of the transmission handle 2, so that the cross beam 111 is avoided, and the transmission handle 2 is effectively rotated.

The screw drive engagement of the core 14 with the glans-sleeve 15 is achieved by having an external screw thread on the upper end side of the core 14 and an internal screw threaded bore in the guide 151 at the lower end of the glans-sleeve 15. The gun core 14 is in axial limiting circumferential rotatable fit with the cross beam 111 through the upper hoop 3 and the lower hoop 3.

The upper end wall of the transmission handle 2 is bent inwards, and the bent angle is an arc angle 22. When the transmission handle 2 abuts against the annular push rod 13, the lower end of the annular push rod 13 is extruded through the arc bending part, and the pushing strength and the stability can be improved.

The lower end of the annular push rod 13 is bent inwards 131, and the structure can increase the contact and pressing area of the lower end of the annular push rod 13 for the upper end of the transmission handle 2, so that the transmission stability is improved.

A knob 141 is provided at a lower end of the core 14 to facilitate rotation of the core 14.

When in specific use, the position of the tortoise head sleeve 15 is adjusted by the rotation of the gun core 14; then the pin shaft 21 is hooked in the hook groove 17, so that the rotary connection of the transmission handle 2 at the lower end of the shell 11 is realized; then the transmission handle 2 is rotated to enable the upper end of the transmission handle 2 to approach towards the lower end of the annular push rod 13 until the transmission handle contacts with the annular push rod 13 and pushes the annular push rod 13, the nail bin and the annular blade to move upwards, and cutting is finished; after the cutting is finished, the transmission handle 2 is rotated reversely, and then the transmission handle 2 is taken down from the hook groove 17. The transmission handle 2 has the characteristics of simple structure, convenient use and low production cost when in use. Meanwhile, the transmission handle is not in direct contact with a human body, so that the transmission handle can be repeatedly used after being taken down after operation, the use cost is further reduced, and only a working assembly needs to be produced when the transmission handle is produced.

In this embodiment, the diameter of the transmission handle 2 is smaller than the diameter of the lower port of the housing, so that the upper end of the transmission handle enters the lower port of the housing to push the annular push rod. Meanwhile, through the arrangement of the diameter of the transmission handle 2 and the caliber of the lower port of the shell, as shown in fig. 2, when the right side surface of the transmission handle 2 is pushed to abut against the inner wall of the lower port of the shell, the annular push rod is explained to move upwards to a proper position, the cutting is completed, and the use safety is improved.

In the first embodiment, the transmission handle rotates relative to the shell from a relative inclination to a relative alignment process, so that the tortoise head sleeve is ejected. As a second embodiment of the present invention, the driving handle can also be rotated from a relative straight line to a relative inclined process, so as to eject the tortoise head sleeve. As shown in fig. 5, the pin is disposed at the upper end of the transmission handle 2, and a central control pushing portion 26 is disposed on the side of the transmission handle for pushing against the lower end of the annular push rod and entering into the lower port of the housing.
