Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a handle and a needle and thread inserter. Background Art

[0002] Among the many current anchor products with needles and threads, according to market research and surgeons' opinions, the number of sutures is sometimes greater than one, and some products require suture needles in addition to threads. This causes problems in that, during the operation, multiple sutures may be mixed together or multiple sutures may be mixed with suture needles, which can easily lead to knots and multiple suture needles being difficult to distinguish. This can greatly reduce the efficiency of the operation and affect the outcome. Summary of the invention

[0003] The object of the present invention is to provide a handle which can be provided with accommodating cavities for placing sutures and suture needles respectively on the outside of the structure, so as to facilitate the arrangement of the sutures and suture needles.

[0004] Another object of the present invention is to provide a needle and thread inserter, which can form a suture, a suture needle and a handle body into an organic whole, and the suture and the suture needle are stored and distributed reasonably, which is conducive to improving the use efficiency of the tool.

[0005] The embodiment of the present invention is achieved as follows:

[0006] A handle comprises a handle body, on which a wire winding groove and a needle and thread accommodating groove are arranged; the needle and thread accommodating groove is arranged on the end surface of the first end of the handle, and the wire winding groove is located on the circumferential surface of the first end of the handle.

[0007] The first end of the handle is designed to be close to the operator's body during surgery, while the other end is the end facing the patient. A needle and thread accommodating groove is provided at the first end of the handle for placing sutures at ordinary times, and the winding ring groove is used for winding the sutures therein at ordinary times. The handle of this structure can separate the sutures and suture needles, avoiding the disadvantage of storing the sutures and suture needles together in the groove cavity of the side wall of the handle in the traditional structure, so that multiple sutures and suture needles can be stored separately, preventing the entanglement of needles and threads caused by the curved shape of the suture needles.

[0008] In a preferred embodiment of the present invention, at least one partition is provided in the needle and thread receiving groove to divide the needle and thread receiving groove into a plurality of cavities. The technical effect is that since one inserter may correspond to different surgeries, different suture needles are required, and the sutures for suturing different parts of the body are also different. Therefore, by dividing one needle and thread receiving groove into a plurality of cavities through a partition, a plurality of suture needles can be placed, which is convenient for taking and placing and easy to use.

[0009] In a preferred embodiment of the present invention, it also includes a wire pressing groove, which is arranged at the end of the first end of the handle body and the outer side wall of the handle body, and the wire winding ring groove is connected to the needle and thread accommodating groove through the wire pressing groove. Its technical effect is that since the suture is still connected with the suture needle after winding, and the suture needle needs to be placed in the needle and thread accommodating groove, and the exposed suture is also easy to wear or dirty during external friction. Therefore, in order to avoid the suture being exposed on the outside of the handle after winding, which affects the storage of the inserter, a wire pressing groove is opened between the wire winding ring groove and the needle and thread accommodating groove, so that the storage of the suture after winding is more concealed.

[0010] In a preferred embodiment of the present invention, the number of the wire pressing grooves is multiple, and the multiple wire pressing grooves are evenly distributed around the circumference of the winding ring groove. The technical effect is that in order to completely wind the suture and place the suture needle, the wire pressing grooves should be set to multiple, so that no matter where the end of the suture is located in the winding ring groove after winding, there can be a corresponding wire pressing groove for introducing the suture needle into the needle and thread accommodating groove.

[0011] In a preferred embodiment of the present invention, a top cover is further included; the top cover is arranged at the end of the first end of the handle body, and is used to block the needle and thread receiving groove. The technical effect is that when the inserter is stored for standby, the needle and thread are in a tangled state and the suture needle is also built into the needle and thread receiving groove, and the top cover can block the needle and thread receiving groove to prevent the suture needle from being exposed, falling or being contaminated.

[0012] In a preferred embodiment of the present invention, one of the top cover and the handle body is provided with an internal thread, and the other is provided with an external thread, and the top cover and the handle body are screwed together through the internal thread and the external thread. The technical effect is that the top cover is screwed into the handle body, and although the top cover is relatively complicated to screw in this structural design, it is tightly connected to the handle body.

[0013] In a preferred embodiment of the present invention, one of the top cover and the handle body is provided with a guide groove, and the other is provided with a guide rail, and the top cover and the handle body are slidably plugged in through the guide groove and the guide rail. The technical effect is that the top cover is slidably plugged in the handle body, which is very convenient for the surgical operator to use with one hand. Only one hand is needed to press and push to open the top cover, quickly take out the suture needle and suture, and carry out the operation in time.

[0014] In a preferred embodiment of the present invention, a traction rope is further included; one end of the traction rope is fixed to the top cover, and the other end is arranged on the handle body. The technical effect is that the traction rope connects the top cover and the handle body together, and the top cover is not easily lost even if it is opened in time.

[0015] In a preferred embodiment of the present invention, it also includes anti-skid patterns; the anti-skid patterns are arranged on the outer wall of the handle body. Its technical effect is that during the operation, the operator holds the handle body and wears gloves or the operation environment is relatively humid. The anti-skid patterns can increase the friction between the operator's palm and the handle, thereby improving the efficiency of the operation.

[0016] A needle and thread inserter comprises a suture, a suture needle and any one of the above handles; the suture needle is arranged at the second end of the handle body through the suture.

[0017] The beneficial effects of the embodiments of the present invention are:

[0018] The handle of the present invention has a wire winding ring groove on the outer wall of one end of the handle body for placing the suture, and a needle and thread accommodating groove on the end of one end of the handle body for placing the suture needle, which is conducive to arranging the suture and the suture needle by the arranging inserter to prevent the suture and the suture needle from being entangled and hindering the surgical operation.

[0019] The needle and thread inserter of the present invention forms the suture, suture needle and handle body into an organic whole, and the suture and suture needle are provided with separate storage cavities on the handle body, and the storage distribution is reasonable, which is conducive to improving the use efficiency of the inserter.
