Description

Technical Field

[0001] The present invention relates to the technical field of thread embedding, in particular to the technical field of thread embedding devices. Background Art

[0002] Acupoint thread embedding is a Chinese medicine method in which absorbable surgical sutures are embedded in specific acupoints to achieve therapeutic effects through continuous stimulation. Acupoint thread embedding combines acupuncture and modern medical technology. The effects of a single thread embedding can last for several days to weeks, which can reduce the trouble of frequent acupuncture. It is very suitable for treating chronic diseases (such as chronic gastritis, asthma and arthritis, etc.), assisting weight loss (regulating metabolism, promoting fat decomposition) and assisting beauty (improving skin problems such as acne and pigmentation, etc.).

[0003] When performing acupuncture thread embedding, doctors usually need to first determine the location of the acupuncture point, then implant the thread into the acupuncture point after disinfection and leave it for a period of time, so that the absorbable surgical suture gradually softens, decomposes, liquefies and absorbs in the human body and continuously stimulates the acupuncture point and produces a therapeutic effect during this period; as shown in the subcutaneous tissue injection device with announcement number CN201684234U, the most common acupuncture thread embedding method at present is to first use tweezers to clamp a cut section of absorbable surgical suture, insert one end of the absorbable surgical suture into the injection needle from the needle tip (i.e. threading) and bend the other end toward the injection needle (see Figure 1 ), and then the injection needle equipped with the absorbable surgical suture is inserted into the skin and pulled out so that the absorbable surgical suture is automatically detached and retained in the subcutaneous tissue during the withdrawal; however, the above threading process is very time-consuming and laborious; in addition, if the exposed end of the absorbable surgical suture is not well kept bent, it may leave the human body together with the injection needle during the withdrawal process. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the prior art and to provide a needle-thread integrated suture embedding device which is easy to use and is not likely to bring out absorbable suture when the needle is pulled out.

[0005] To achieve the above-mentioned purpose, the present invention proposes a needle-thread integrated suture embedding device, comprising a needle handle, a needle rod, a locking thread ring and absorbable surgical suture, the top end of the needle rod is connected to the needle handle and the bottom end passes through the locking thread ring along the rod hole and is provided with a blade portion with an inclined surface, one end of the absorbable surgical suture extends from the blade portion into the rod hole of the needle rod and the other end passes through the locking thread ring along the wire groove after being bent.

[0006] Preferably, the wire groove is an L-shaped slot with one end extending through the outer edge of the locking wire ring, and the absorbable surgical suture passes through the wire groove from the closed end.

[0007] Preferably, the device further comprises a protective cover, which is simultaneously arranged outside the needle handle, the needle rod, the locking thread ring and the absorbable surgical suture.

[0008] Preferably, the needle handle is provided with a wire channel that penetrates from the side wall to the bottom end and accesses the rod hole. The absorbable surgical suture can first pass through the needle handle and the needle rod along the wire channel and the rod hole in sequence, then bend and pass through the wire locking ring along the wire groove. The needle handle is also provided with a knife channel that penetrates from the wire channel to the top end. A knife rod is installed in the needle handle and can move up and down along the knife channel to cut the absorbable surgical suture.

[0009] Preferably, the wire channel is a bent channel with a bent portion, and the bent portion is lower than the connection position of the knife channel and the wire channel.

[0010] Preferably, the needle handle is provided with a guide cylinder extending outward at the entrance of the wire channel.

[0011] Preferably, the top end of the knife rod is connected to the knife handle, and the bottom end extends into the needle handle along the knife channel. A return spring is also sleeved outside the knife rod. The upper and lower ends of the return spring respectively abut against the knife handle and the needle handle to use the elastic force to prevent the needle handle from entering the wire channel in the natural state.

[0012] Preferably, the knife handle and the needle handle are respectively provided with an upper convex platform and a lower convex platform for installing the return spring at the adjacent surfaces.

[0013] Preferably, a flexible hose is further included. The flexible hose is installed at the entrance of the wire channel and sleeved outside the absorbable surgical suture.

[0014] Preferably, a pipe groove is provided outside the needle handle. The flexible hose can be spirally wound around the needle handle along the pipe groove and the end is fixed by a pipe clamp installed on the needle handle.

[0015] Advantages of the present invention: 1) By directly providing the needle rod with a bent absorbable surgical suture at the time of leaving the factory, the clinical thread embedding operation can be simplified (the steps of cutting the thread and inserting the thread can be omitted), the thread can be embedded immediately upon insertion, one needle for one acupoint (the needle is discarded upon withdrawal), which is convenient for clinical use and improves the treatment efficiency; 2) By adding a wire locking ring outside the needle rod, the absorbable surgical suture can be temporarily locked by the wire locking ring before use to assist the needle rod in feeding the thread, avoiding accidentally pulling the absorbable surgical suture out of the body again when the needle rod is withdrawn, and effectively reducing the probability of repeated needle insertion (reducing the pain caused by the needle prick); 3) By using an L-shaped slot that penetrates to the outer edge of the wire locking ring as the wire groove above the wire locking ring, not only can the special shape be used to keep the absorbable surgical suture in a bent state as much as possible before thread embedding, but it does not affect the automatic vertical detachment of the absorbable surgical suture from the wire locking ring during thread embedding. Moreover, even if the absorbable surgical suture prematurely detaches from the wire locking ring, it can be quickly reset along the outer edge. 4) By adding a wire channel and a knife - feeding channel that are connected and communicated above the needle handle, and threading the absorbable surgical suture through the needle handle and the needle shaft along the wire channel and the rod hole in sequence, the absorbable surgical suture can be cut by the knife shaft that moves up and down along the knife - feeding channel, so that the needle shaft can achieve suture replenishment; 5) By installing a hose sleeved outside the absorbable surgical suture at the entrance of the wire channel, and spirally winding the hose around the needle handle along the pipe groove and fixing the end through a pipe clamp installed on the needle handle, the exposure of the absorbable surgical suture can be avoided as much as possible before use, and at the same time, the absorbable surgical suture and the hose are prevented from affecting the doctor's suture - embedding operation.

The top end of the needle rod 2 is connected to the needle handle 1, and the bottom end passes through the thread locking ring 3 along the rod hole 31 and is provided with a blade part having an inclined surface. One end of the absorbable surgical suture extends into the rod hole of the needle rod 2 from the blade part, and the other end passes through the thread locking ring 3 along the thread groove 32 after being bent; wherein, there is an interference fit between the main needle rod 2 and the thread locking ring 3 (at the rod hole 31); the absorbable surgical suture is made of protein thread (such as catgut); the needle rod 2 is made of stainless steel rod (not easy to bend and deform, and enabling the blade part to quickly break through the skin during puncture), and the needle handle 1 is made of stainless steel handle (such as formed by winding stainless steel wire).

[0019] The thread groove 32 is an L-shaped groove with one end penetrating through to the outer edge of the thread locking ring 3, and the absorbable surgical suture passes through the thread groove 32 from the closed end.

[0020] In addition, during sales, it adopts a one-device-one-packaging mode, which is convenient for clinical selection; during actual production, the needle rod 2 can be set with different specifications (i.e., different lengths and diameters) according to clinical operation requirements.

[0021] The working process of this embodiment is as follows: When in use, hold the thread locking ring 3 with the left hand, and hold the needle handle 1 with the right hand. First, push the needle rod 2 down along the thread locking ring 3 until it pierces the skin and sends the absorbable surgical suture into the body, then release the left hand and directly pull out the needle rod 2 from the body (the absorbable surgical suture will adhere to the subcutaneous tissue); before embedding the thread, the thread locking ring 3 can also be moved up along the needle rod 2 in advance to make the absorbable surgical suture detach from the thread locking ring 3 in advance, and then directly use the needle rod 2 for puncture and needle pulling to bury the absorbable surgical suture into the body.

[0022] In addition, it is discarded after use, achieving one needle for one acupoint (inserting the needle immediately to embed the thread), and omitting the operations of cutting the thread and threading the thread in the traditional method.

[0023] Embodiment Two: Refer to Figure 4 , it further includes a protective sleeve 4, and the protective sleeve 4 is simultaneously sleeved outside the needle handle 1, the needle rod 2, the thread locking ring 3 and the absorbable surgical suture; wherein, the length of the protective sleeve 4 can be slightly shorter than the sum of the lengths of the needle handle 1 and the needle rod 2.
