[0002] Currently, with the continuous development of medical technology, arthroscopic surgery has become a routine diagnostic and treatment method in orthopedic surgery. Among all endoscopic procedures of the body, arthroscopic surgery has the most comprehensive functions and the widest range of applications, such as meniscus repair and rotator cuff tears. Generally, after surgery on the bone and joint, sutures are used to suture the tissues inside the cavity, and then the sutures need to be cut.

[0003] The suture cutter in the existing technology is bulky and requires the suture to be threaded from the end of the suture, and then the head of the suture cutter is pushed from outside the body along the suture to the end of the knot, which increases the operation time and thus increases the patient's pain. Utility Model Content

[0004] This invention designs and develops a thread cutter that can cut at any position on the suture, overcoming the defect of existing instruments that require threading from the end of the suture when cutting.

[0005] The technical solution provided by this utility model is as follows:

[0030] The large opening can accommodate two sutures at the same time, and the sharp blade can also cut two sutures at the same time, so that doctors do not have to cut them one by one, doubling the cutting efficiency.

[0031] By keeping the pliers tip a certain distance from the cutting position, a safe length of thread can be reserved at the knot position, effectively controlling the length of the thread end and preventing problems such as loosening of the knot or excessively long thread ends caused by overcutting.

[0032] The shearing section uses high-strength, high-hardness metal to ensure that the product will not chip or break under more than 500 shearing cycles, effectively improving mechanical strength and service life, ensuring that the jaws will not break and remain in the cavity, and significantly reducing the risk of medical accidents.

[0033] The handle's shape and spacing were designed based on the small to medium hand size of Chinese people. The ergonomic design helps to reduce fatigue even during long surgical card removal procedures. Attached Figure Description

[0040] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0041] like Figure 1-6 As shown, this utility model provides a suture cutter that, through the cooperation of the tip tube and the jaws, can cut sutures at any position, overcoming the defect of existing instruments that require threading the suture from the end when cutting sutures. It includes: jaws 110, lugs 111, a first jaw connecting hole 112, a second jaw connecting hole 113, a blade 114, a flat mouth 120, a receiving groove 121, a first thread inlet 122, a second thread inlet 123, a flat mouth hole 124, a tip tube 130, a first operating part 140, a second operating part 150, a connecting rod 160, a connecting rod hole 161, and a suture to be cut 200.

[0042] The tip tube 130 has a cylindrical structure and a receiving cavity is provided inside the tip tube 130. One end of the tip tube 130 is a flat opening 120 with an upward opening, forming a receiving groove 121 with an upward opening for accommodating the jaws 110. The jaws 110 are rotatably disposed within the receiving groove 121 of the flat opening 120. A first cable inlet 122 is disposed on the end face of one end of the flat opening 120 and communicates with the receiving groove 121. A second cable inlet 123 is disposed on one side of the flat opening 120 and communicates with the receiving groove 121. The connecting rod 160 is coaxially disposed in the receiving cavity of the tip tube 130. One end of the connecting rod 160 is rotatably connected to the jaws 110, and the other end of the connecting rod 160 is rotatably connected to one end of the first operating part 140. One end of the second operating part 150 is fixedly connected to the outer wall of the other end of the tip tube 130. The first operating part 140 and the connecting rod 160 are rotatably connected to form a driving structure. The connecting rod 160 is driven by the first operating part 140 to rotate the jaws 110, forming a shearing structure with the receiving groove 121.

[0043] Two lugs 111 are spaced apart at one end of the jaws 110, and the other end of the jaws 110 extends toward one side of the second cable inlet 123 to form the pliers blade section. On both sides of the receiving groove 121, on the sidewalls of the flat jaw section 120, two flat connecting holes 124 are formed opposite each other; above the two lugs 111, two first jaw connecting holes 112 are formed opposite each other, and below the two lugs 111, two second jaw connecting holes 113 are formed opposite each other. A connecting rod hole 161 is formed at one end of the connecting rod 160.

[0044] The connecting rod hole 161 is located between and matches the two first jaw connection holes 112. A connecting rod pin passes through the first jaw connection holes 112 and the connecting rod hole 161, rotatably connecting the connecting rod 160 and the jaws 110 to form a drive structure. Two second jaw connection holes 113 match two flat-mouth connection holes 124 and are riveted together to achieve a rotatable connection, forming a rotating structure. The diameter of the rivet is smaller than the diameter of the second jaw connection holes 113 and the flat-mouth connection holes 124, creating a gap between the rivet and each connection hole to facilitate rotation.

[0045] A shearing blade is provided on the side of the jaw 110 facing the receiving groove 121. The flat part 120 is rotatably connected to the connecting rod 160 through the jaw 110 to form a jaw shearing structure.

[0046] In this invention, as a preferred embodiment, both the first thread inlet 122 and the second thread inlet 123 are U-shaped structures. The design of the front end and side openings allows for loading of the suture at any position, eliminating the need to load the suture from the end and then cut it.

[0047] The other ends of the first operating part 140 and the second operating part 150 are both annular structures, wherein the annular structure of the first operating part 140 is used to accommodate a finger, and the annular structure of the second operating part 150 is used to accommodate a thumb.

[0048] like Figure 6 As shown, during operation, the suture cutters are inserted into the joint cavity. After determining the cutting position, the suture is secured by the first suture inlet 122 and the second suture inlet 123 on the front and side. The thumb and finger are inserted into the second operating part 150 and the first operating part 140, and the finger is driven to rotate the drive linkage 160, which in turn rotates the jaws 110 to perform the cutting.

[0049] The novel medical surgical suture cutter provided by this utility model solves the problem of inconvenience in suture cutting operations and the need to thread the suture from the end of the suture when using existing medical devices.

[0050] The design with openings at the front and sides allows for loading at any position along the suture line, eliminating the need to load the suture line at the end for cutting, thus simplifying operation and improving efficiency.

[0051] The large opening can accommodate two sutures at the same time, and the sharp blade can also cut two sutures at the same time, so that doctors do not have to cut them one by one, doubling the cutting efficiency.

[0052] By keeping the pliers tip a certain distance from the cutting position, a safe length of thread can be reserved at the knot position, effectively controlling the length of the thread end and preventing problems such as loosening of the knot or excessively long thread ends caused by overcutting.

[0053] The shearing section uses high-strength, high-hardness metal to ensure that the product will not chip or break under more than 500 shearing cycles, effectively improving mechanical strength and service life, ensuring that the jaws will not break and remain in the cavity, and significantly reducing the risk of medical accidents.

[0054] The handle's shape and spacing were designed based on the small to medium hand size of Chinese people. The ergonomic design helps to reduce fatigue even during long surgical card removal procedures.

[0055] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
