Description

implant for surgery

technical field

The invention relates to an implanter for surgery and belongs to the technical field of medical instruments.

Background technique

In the knee joint, the meniscus has a very important function: it distributes the weight on the joint to relieve the load, performs the joint motion smoothly and contributes to the stability, however, the meniscus can be damaged due to excessive movement, aging, or Pain due to abnormal activity. If the meniscus is injured, function is impaired and pain occurs when walking. Occurs mainly when the knee is extended and bent. When the damage becomes serious, its own function will not be reflected, and its wear and aging will be accelerated. Before that happens, we can suture or treat this damage with actual surgery.

At present, meniscus suture surgery is one of them, and most of the products are implanted manually. The inconvenient operation and operation of this type of operation greatly limit the operation time, and the user should carefully check whether the accessories of related products are complete. During the implantation process, the device must be manually reset to facilitate reuse. Requirements, this not only delays time, but also disperses the user's energy and attention, and there is a great potential safety hazard.

Contents of the invention

The object of the present invention is to provide an implanter for surgery, capable of rapidly implanting implants into the human body twice in a row.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical solution: an implanter for surgery, including a housing, a trigger, an implant knife and a hollow tube, the housing is provided with a propulsion assembly, a torsion spring and a limit Push post, one end of the trigger is connected to the propulsion assembly through a limiting push post, the propulsion assembly is connected to one end of the hollow tube through a stop sleeve, and the implant knife is set at the end of the hollow tube away from the propulsion assembly ; The implant knife is a hollow tube, one end of which is provided with a spike, and two implant objects are placed in the implant knife.

The housing is made of medical grade plastic. Implants refer to substitutes that are implanted in the human body and can replace the functions of the corresponding parts.

In the aforesaid surgical implanter, the propulsion assembly includes a tension spring, a fixing tube, a propulsion piece, a sliding base and a sheath fixing seat, one end of the tension spring is fixed on the housing, and the other end Connected with the sliding base, the sliding base and the sheath fixing seat are both arranged on the fixing tube, the sliding base is located near the tail end of the fixing tube, and the sheath fixing seat is located near the head end of the fixing tube position; one end of the trigger is connected to the sliding base; a track is arranged on the fixed pipe, and one end of the pusher is connected to the sliding base. The pusher is located in the track and can move back and forth along the track.

In the aforementioned implanter for surgery, the front half of the pusher is a soft rod, the second half of the pusher is a hard rod, the soft rod is located in the hollow tube, and the rod is so hard that the rod is located in the hollow tube. in the fixed tube.

In the aforementioned implanter for surgery, the position-limiting sleeve includes a sleeve part, which extends from the inside of the housing to the outside of the housing, and the head end of the fixing tube is connected to the hollow tube outside the housing through the sleeve part. , the limit sleeve is fixed on the sheath holder.

In the aforementioned surgical implanter, the housing includes a handle portion, and the handle portion is provided with at least 2 anti-slip grooves and at least 2 reinforcing ribs. Anti-slip grooves and reinforcing ribs play an anti-skid role.

In the aforementioned implanter for surgery, a cylindrical rod is arranged on the housing, the trigger is arranged on the housing through the cylindrical rod, a weight-reducing groove is arranged on the body of the trigger, and the edge position of the body of the trigger There is also a recessed part on the trigger, an anti-off groove is provided at the end of the trigger away from the housing, and a raised part is also provided on the body of the trigger. In order to prevent fingers from being pinched when the trigger is pulled, a raised portion is provided on the trigger body. In order to prevent slippery hand problems when pulling the trigger, anti-slip grooves and anti-loosening grooves are set on the trigger body. The design of the weight-reducing groove can greatly reduce the overall weight of the implanter, making it easier to use.
