A surgical scissors

Abstract

The utility model discloses a surgical auxiliary scissors, which relates to the field of medical scissors, and comprises two scissor rotating arms, which are symmetrical to each other and connected in an X-shape, and the hand-held ends of the two scissor rotating arms are connected in a rotational manner along the extension direction thereof with a handle ring, and the surface end of the handle ring is connected in a rotational manner with a linkage rod. The end of the linkage rod is driven to move by an adjustment component, so that the handle ring is bent toward one side of the scissor rotating arm. At this time, the handle ring can be held with the right hand (with the most comfortable scissor holding technique) to cut objects, avoiding blocking of the line of sight, and then the adjustment rod is flipped so that the clamping plate is located in front of the tip of the scissor rotating arm. At this time, the two clamping plates can be driven to approach for clamping action, which not only avoids the back of the hand from arching to block the line of sight, but also allows the scissors to be held with the usual method, thereby improving the operational stability, and at the same time, the function conversion between cutting and clamping can be performed, so as to achieve the purpose of dual-use interchangeability and improve practicality.

Description

Technical Field

[0001] The utility model relates to the technical field of medical scissors, in particular to a pair of surgical auxiliary scissors. Background Art

[0002] In ENT surgery, surgical scissors are frequently used. Surgical scissors are a common medical device used in clinical surgery, mainly used to cut rough soft tissues such as skin or muscle. They can also be used to separate tissues, that is, insert the tip of the scissors into the gap between tissues to separate connective tissues without large blood vessels. There are also many types of surgical scissors to cope with different scenarios.

[0003] Since the size of the wound for inserting medical instruments in ENT surgery is limited, although there are three ways to hold the surgical scissors, namely, forward scissors, reverse scissors and vertical scissors, the hand will be arched during the holding process, which will affect the operator's line of sight to a certain extent. However, when the scissors are held in a way that does not block the line of sight, the hand will be twisted, which is inconvenient to operate. Moreover, the current surgical scissors have a relatively single function and can only be used as scissors. In actual operation, different tools are needed to clamp and pick, which is not very practical. Utility Model Content

[0004] The purpose of the present utility model is to provide a surgical auxiliary scissors in order to solve the above problems, as described below.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] When using the above-mentioned surgical auxiliary scissors, fingers can be inserted into the handle ring to drive the two scissor rotating arms to cross-rotate and cut objects. The end of the linkage rod can be driven to move by the adjustment component to make the handle ring bend toward one side of the scissor rotating arm. At this time, there is a certain angle between the handle ring and the scissor rotating arm. At this time, the handle ring can be held with the right hand to cut objects to avoid blocking the line of sight. Then the adjustment rod can be flipped 180 degrees so that the splint is located in front of the tip of the scissor rotating arm. At this time, the two splints can be driven close to each other for clamping action.

[0008] Preferably, the hand-held ends of the scissors rotating arms are each provided with a half-open rotating groove, a connecting block is rotatably connected in the half-open rotating groove, and the connecting block is fixedly connected to the end of the handle ring.

[0009] Preferably, the adjustment assembly includes a movable groove extending through the scissors rotating arm, a threaded rod is rotatably connected in the movable groove, a threaded sleeve is threadedly connected to the threaded rod, and the other end of the linkage rod is rotatably connected to the surface of the threaded sleeve.

[0010] Preferably, the cross-sections of the movable groove and the threaded sleeve are both square in design.

[0011] Preferably, a rotating wheel groove is formed through the rotating arm of the scissors, and the rotating wheel groove is located at the end of the movable groove, and the end of the threaded rod extends into the rotating wheel groove and is fixedly connected with a thumbwheel.

[0012] Preferably, the bolt connector includes a through hole formed on the adjusting rod, a bolt is inserted into the through hole, and bolt holes threadably connected to the bolt are formed on both sides of the surface of the scissors rotating arm.

[0013] Preferably, the surfaces of the two clamping plates are provided with anti-slip patterns.

[0014] The beneficial effects are:

[0015] The end of the linkage rod is driven to move by the adjustment component so that the handle ring is bent toward one side of the scissors rotating arm. At this time, the handle ring can be held with the right hand (in the most comfortable way of holding the scissors) to cut objects to avoid blocking the line of sight. The adjustment rod is then flipped so that the clamping plate is located in front of the tip of the scissors rotating arm. At this time, the two clamping plates can be driven close to perform a clamping action, which not only avoids the back of the hand from arching to block the line of sight, but also allows the scissors to be held in the usual way, thereby improving operational stability. At the same time, the function can be converted between cutting and clamping, achieving the purpose of interchangeable use and improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS
