Anastomat for achilles tendon

Abstract

The invention discloses an anastomat for achilles tendon. According to the technical scheme, two handle parts are hinged to a positioning shaft; connecting shafts are arranged on the two clamping parts; the connecting shafts are rotatably connected with the end part, positioned between the pair of aiming arms, of the handle parts; a first driving wheel and a second driving wheel are arranged on the positioning shaft; the first driving wheel and the second driving wheel are coaxially arranged on the positioning shaft and are fixed relative to the positioning shaft; a first driven wheel and a second driven wheel which are in mutual transmission with the first driving wheel and the second driving wheel are respectively arranged on the two connecting shafts; through mutual transmission betweenthe first driving wheel and the first driven wheel and between the second driving wheel and the second driven wheel, the included angle between the straight line where the clamping part is located and the straight line where the sighting arm is located is always consistent, the clamp holes extend in the length direction of the clamping parts, the length of openings of the clamp holes is larger than that of the threading holes, and the problems that in the prior art, harm to the body of a patient is large, and threading is inconvenient are solved.

Description

technical field [0001] The invention relates to a medical device, more specifically to a stapler for the Achilles tendon. Background technique [0002] Achilles tendon rupture requires a special Achilles tendon stapler for surgical repair. Although the use of a special Achilles tendon stapler is short in operation time and less traumatic to the human body, the Achilles tendon stapler is expensive and is a one-time product. The medical expenses are expensive, and now we have found a patent with the application number CN201410829808.0. The patent designs the ring pliers body, the aiming bracket and the paired aiming arms extending from the aiming bracket. Through the hole on the aiming arm and the ring pliers body The corresponding holes on the pliers allow the thread to pass through the Achilles tendon. It is similar in structure to the Achilles tendon stapler and is also very convenient in operation, but there are still defects. The position of the hole will be offset from ...

[0002] Achilles tendon rupture requires a special Achilles tendon stapler for surgical repair. Although the use of a special Achilles tendon stapler is short in operation time and less traumatic to the human body, the Achilles tendon stapler is expensive and is a one-time product. The medical expenses are expensive, and now we have found a patent with the application number CN201410829808.0. The patent designs the ring pliers body, the aiming bracket and the paired aiming arms extending from the aiming bracket. Through the hole on the aiming arm and the ring pliers body The corresponding holes on the pliers allow the thread to pass through the Achilles tendon. It is similar in structure to the Achilles tendon stapler and is also very convenient in operation, but there are still defects. The position of the hole will be offset from the hole on the aiming arm, and the position of the hole on the body of the ring pliers needs to be found again when the line passes through the hole on the aiming arm, and the effective area of ​​the opening of the hole on the body of the ring pliers will be reduced, that is, when needed In the case of threading multiple threads, the number of threading threads is reduced, and multiple positioning is required; and when the ring forceps body is opened and extended into the human body to clamp the Achilles tendon, the side walls of the left forceps body and the right forceps body against the Achilles tendon There is an included angle, that is, both the left clamp body and the right clamp body are in conflict with the end edge of the Achilles tendon stump, the clamping area is small, the Achilles tendon stump bears a large force, and it is easy to cause damage to the Achilles tendon stump, and the left clamp body and the top of the right clamp body will stretch the human skin, causing harm to the patient, and further improvement is needed
