Technical Field

The invention relates to the field of medical instruments, in particular to an automatic circumcision device.

Background

With the development and clinical verification of medical science and technology, the cutting and suturing principle of circumcision is gradually accepted by clinical academia. Compared with the traditional prepuce cutting operation, the circumcision suturing device has the advantages of completing cutting and suturing in one step, along with quick operation, less bleeding, less pain, smooth cutting and the like. At present, the circumcision stitching instrument is a manual hair-striking type; parameters such as the propelling force, the retention time after propelling cutting and the like are controlled by the experience of a doctor, when the force is insufficient, the phenomena of continuous and partial cutting of the foreskin and the like are easy to occur, and when the force is too large, the phenomena of too deep cutting, incapability of pulling out the cutter due to the fact that the cutter is deeply sunk into the anvil and the like are easy to occur.

Therefore, the prior art provides an electric circumcision device, which drives a circumcision knife to advance through a motor arranged in the circumcision device to carry out a circumcision operation; however, the electric ring cutter is not detachable, and must be discarded after completing the excision operation, which not only wastes the driving components such as the motor, but also causes the operation cost to rise.

Referring to fig. 1 to 3, the automatic circumcision apparatus of the present embodiment includes: a housing 100; a seat 420 fixedly connected to the housing 100; a ring cutting mechanism 300 disposed within the housing 100; a driving mechanism 200 disposed in the housing 100 for pushing the circular cutting mechanism 300 to move toward the balanus seat 420; the drive mechanism 200 is provided separately from the ring cutting mechanism 300.

By applying the automatic circumcision device of the embodiment, when an operation is performed, a user can firstly place the ghost head in the glans penis seat 420, wrap the foreskin at the periphery of the glans penis seat 420, then the driving mechanism 200 starts to operate, and drive the circumcision mechanism 300 to move towards the glans penis seat 420, so that the circumcision mechanism 300 can cut off redundant foreskin surrounding the glans penis seat 420, only the circumcision mechanism 300 needs to be separated from the driving mechanism 200 after the operation is contacted, and the circumcision mechanism 300 needs to be discarded, only a new circumcision device needs to be replaced when an operation is performed on other patients, the whole circumcision device does not need to be discarded, and the instrument cost in the operation process is effectively reduced.

The driving mechanism 200 can be separated from the circular cutting mechanism 300 in multiple ways, and at the same time, the driving mechanism 200 can push the circular cutting mechanism 300 to move towards the balanus seat 420, so that the foreskin wrapped on the balanus seat 420 is cut off; for example, the housing 100 is provided with an electromagnet, and when the electromagnet is powered on, repulsive force can be applied to the circular cutting mechanism 300 through the magnetic force, so that the circular cutting mechanism 300 moves towards the glans base 420, and the foreskin wrapped outside the glans base 420 is cut off; or a slider provided on the housing 100 is driven by the motor 210 or a driver of the air cylinder, and the circular cutting mechanism 300 is provided to be detachably connected to the slider; the sliding block arranged on the shell 100 can be driven by the driver of the motor 210 or the air cylinder, and the sliding block is abutted to the circular cutting mechanism 300 forwards and pushes the circular cutting mechanism 300 to be pushed forwards, at the moment, the sliding block and the circular cutting mechanism 300 are not connected and only abutted, so that the circular cutting structure can be conveniently disassembled.

It should be noted that the driving mechanism 200 of the present embodiment refers to a mechanism that drives the ring-cutting mechanism 300 to advance through a driver such as a motor 210, an air cylinder, or a hydraulic cylinder without depending on human power, and therefore the structure that pushes the ring-cutting knife 340 to advance by pressing the handle with human power in the prior art does not belong to the driving mechanism 200 of the present embodiment.

As shown in fig. 3, the ring cutting mechanism 300 includes: a sleeve 320 detachably connected to the housing 100; the ring-cutting knife 340 is in sliding fit with the sleeve 320, and the ring-cutting knife 340 can move towards the balanus seat 420 under the abutting of the driving mechanism 200; when the circular cutting operation is completed, the entire circular cutting mechanism 300 can be removed from the housing 100 by simply separating the sleeve 320 from the housing 100, and then replaced with a new circular cutting mechanism 300.

Further, in order to facilitate rapid suturing of the wound after circumcision of the foreskin, the circumcision mechanism 300 further includes a staple pushing assembly 330, the circumference of the circumcision knife 340 is fixedly connected with the staple pushing assembly 330, the staple pushing assembly 330 has a plurality of staple cartridges distributed along the circumference of the circumcision knife 340, and the staple cartridges are used for accommodating suturing staples; before circular cutting, a suturing nail can be placed in the nail bin; when the driving mechanism 200 is started, the staple pushing assembly 330 and the circular cutting knife 340 are pushed together, so that the circular cutting mechanism 300 can push out the suturing staples reserved in the staple cartridge to the wound to facilitate suturing on the premise of realizing the circular cutting function.

The specific structure of the staple pushing assembly 330 can refer to the structure disclosed in CN 105054992A.

In order to facilitate the removal of the penis after the ring cutting, the ring cutting mechanism 300 further comprises a return spring, and the return spring abuts between the sleeve 320 and the ring cutting knife 340; when the driving mechanism 200 is operated reversely, the return spring can make the ring-cutting knife 340 which loses the propelling power automatically retreat and return to the initial state, so as to be convenient for taking down the penis which is finished with the operation.

As shown in fig. 3, the ring cutter further comprises an annular end cap 130, the annular end cap 130 being detachably connected to the housing 100, the annular end cap 130 being capable of abutting a flange provided on the sleeve 320; during the operation, the interior of the annular end cap 130 may facilitate the threading of the guide rod 430 and the advancement of the ring cutter 340; after the procedure is complete, the end cap may be removed from housing 100 such that sleeve 320 is unsecured from housing 100, and the entire ring cutting mechanism 300, including sleeve 320, may then be removed for replacement.

The annular end cap 130 and the housing 100 can be detachably connected in various ways, such as connecting the annular end cap 130 and the housing 100 by screws or pins, or screwing the annular end cap 130 and the housing 100.

As shown in fig. 3, in order to fix the glans penis holder 420 on the housing 100 and prevent the glans penis holder 420 from interfering with the foreskin to be cut off, the glans penis holder 420 is connected with a guide rod 430, the guide rod 430 penetrates through the driving mechanism 200, and the guide rod 430 is fixedly connected with the housing 100; at this time, the guide rod 430 can fix the glans penis seat 420 along the middle position of the glans penis seat 420, and the prepuce to be excised can be wrapped around the glans penis seat 420.

As shown in fig. 1 and 2, in order to facilitate the detachment of the glans 420 from the housing 100, a fastening nut 410 is connected to the rear side of the housing 100, and a guide rod 430 is threadedly engaged with the fastening nut 410; at this time, the guide rod 430 is unscrewed from the fastening nut 410, and the glans 420 can be detached.

Further, to facilitate the detachment of the guide bar 430, the fastening nut 410 may also be provided to be detachably coupled thereto.

As shown in fig. 2 and 4, in order to facilitate the holding of the circumcision instrument and to further improve the compactness of the circumcision instrument, a handle 110 is provided on the housing 100, and the driving mechanism 200 is partially located inside the handle 110.
