Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an electric circumcision stapler with a circumcision knife that is easy to disassemble. Background Art

[0002] The circumcision stapler is a medical device often used in surgical operations on the foreskin tissue of the male penis. In general surgical treatment, the circumcision stapler is often used to complete the cutting and closing function of the tissue. The circumcision stapler consists of a circumcision knife, a gun nail and a driving component. The driving component squeezes the circumcision knife to cut the foreskin and the gun nails suture the remaining tissue to achieve intraoperative hemostasis.

[0003] At present, the circumcision knife is embedded in the driving sleeve through a pin structure, and the driving sleeve is installed in the casing. When disassembling and cleaning after the operation, the driving sleeve is taken out from the casing as a whole, and the pin on the driving sleeve is lifted by a tool to deform and detach from the circumcision knife, so that the circumcision knife can be restricted and detached from the driving sleeve. After multiple deformations, the pin is prone to aging and its service life is reduced. Utility Model Content

[0024] See also Figure 1-3 The utility model provides a technical solution: an electric circumcision stapler with a conveniently detachable circumcision blade, comprising a body 10, a holster 11 fixedly mounted on the body 10, a detachable connection between the holster 11 and the body 10, and further comprising:

[0025] The driving sleeve 13 is slidably inserted into the holster 11; the outer wall of the driving sleeve 13 and the inner wall of the holster 11 are in contact with each other.

[0026] The circular cutting knife 14 is slidably inserted into the driving sleeve 13; the circular cutting knife 14 is slidably inserted into the driving sleeve 13 from the end of the driving sleeve 13, and there is a step in the driving sleeve 13. After the circular cutting knife 14 hits the step, it cannot continue to move;

[0027] The self-locking structure includes a flip plate 15, which is rotatably connected to the driving sleeve 13 and has a locking position on the rotation stroke of the flip plate 15. In the locking position, the flip plate 15 fixes the circumcision knife 14. The circumcision knife 14 is inserted into the driving sleeve 13, and the flip plate 15 is rotated so that one end of the flip plate 15 is embedded in the circumcision knife 14. When the driving sleeve 13 is placed in the holster 11, the inner wall of the holster 11 contacts the flip plate 15 to fix it. When the driving sleeve 13 is placed in the holster 11, the circumcision knife 14 is passively fixed, and the installation is convenient. Similarly, when disassembling after surgery, after removing the driving sleeve 13, the flip plate 15 loses the restriction of the holster 11, and its angle can be flipped, so that the flip plate 15 is separated from the circumcision knife 14, and the circumcision knife 14 can be disassembled from the driving sleeve 13. Compared with the modified bayonet structure, its service life is longer and the disassembly is faster.

[0028] A notch 141 is formed on the circular cutting knife 14, and a clamping block 154 is provided at one end of the flip plate 15. In the locked position, the clamping block 154 is embedded in the notch 141. In the locked position, the upper surface of the flip plate 15 contacts the inner wall of the holster 11, the flip plate 15 is fixed, and the clamping block 154 is embedded in the notch 141, so that the circular cutting knife 14 is moved toward the outside of the driving sleeve 13, thereby fixing the circular cutting knife 14.

[0029] In the locking position, the upper surface of the flip plate 15 is fitted with the inner wall of the driving sleeve 13. The flip plate 15 is fitted with the driving sleeve 13 so that the angle of the flip plate 15 is fixed to fix the annular cutter 14.

[0030] Pins 151 are fixedly installed on both sides of the flip plate 15, and the pins 151 are rotatably connected to the drive sleeve 13. The setting of the pins 151 ensures that the flip plate 15 and the drive sleeve 13 can rotate to ensure that the flip plate 15 can change its angle.

[0031] The driving sleeve 13 is provided with an insertion groove 131, and the pin 151 passes through the insertion groove 131. A limit block 152 is detachably installed in the insertion groove 131, and the limit block 152 is adapted to the pin 151. The insertion groove 131 provided on the driving sleeve 13 can be used for assembling the pin 151, and the limit of the limit block 152 makes the pin 151 only rotate in the insertion groove 131.

[0032] The shape of the limit block 152 is set to be "T"-shaped, and the limit block 152 is installed in the insertion groove 131 by a bolt 153. The limit block 152 is set to be detachable, so that the flip plate 15 can also be disassembled, so that the flip plate 15 can be replaced after the flip plate 15 is worn.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
