Abstract
Description
Technical Field
[0001] The present invention relates to a retractor, a retractor suturing device and a retractor puncturing device, and in particular to an integrated retractor, a retractor suturing device and a retractor puncturing device. Background Art
[0002] With the development of modern medicine, minimally invasive surgery has become the development direction of surgical operations. Minimally invasive surgery has the advantages of less trauma, faster recovery, and less pain. It is the common goal and direction pursued by modern medicine. In existing laparoscopic abdominal surgeries, it is necessary to make an incision in the abdominal skin and place a 5mm trocar, 10mm trocar or 12mm trocar puncture to establish a channel between the abdomen and the outside world. Through the puncture channel established by the puncture, surgical instruments are placed to assist in the surgical operation. During the laparoscopic operation, if the tissue in the surgical area is pulled or exposed inconveniently, it is necessary to make another skin incision and insert a new puncture again, increasing the number of punctures and puncture incisions. In addition, the insertion points of existing abdominal punctures are all incisions of more than 5mm. After the operation, all puncture holes need to be sutured and closed. Since the wound is large, a large scar will be formed after suturing, affecting the beauty of the wound. Summary of the invention

DETAILED DESCRIPTION
[0048] Embodiment 1:
[0049] The present invention provides an integrated traction suture device, such as Figure 1 As shown, it includes a pulling wire and a medical suture needle 2.
[0050] The pulling wire is made of elastic metal or memory metal, and the memory shape can be restored under certain temperature conditions. The pulling wire includes a head pulling rope 11 and a tail knot, and the tail knot is a single spring-shaped structure 5.
[0051] The front end of the head pulling rope 11 is fixedly connected to the medical suture needle 2, and the rear end of the head pulling rope 11 is connected to one end of the tail knot of the single spring-like structure 5, and the other end of the tail knot of the single spring-like structure 5 is empty.
[0052] Embodiment 2:
[0053] like Figure 2 As shown, the difference between Example 2 and Example 1 is:
[0054] One end of the head pulling rope 11 connected to the tail of the single spring-like structure 5 is provided with an S-shaped structure 4 (that is, the end of the head pulling rope 11 connected to the tail of the single spring-like structure 5 is wound into an S-shaped structure 4), which can trap and lock the tissue 6.
[0055] Embodiment 3:
[0056] like Figure 3 As shown, the difference between Example 3 and Example 1 is:
[0057] The tail knot is formed by five spring-type structures directly connected in series, wherein two relatively sparse spring-type structures 51 and three relatively dense spring-type structures 52 are arranged alternately with the three relatively dense spring-type structures 52 and the two relatively sparse spring-type structures 51.
[0058] Embodiment 4:
[0059] like Figure 4 As shown, the difference between Example 4 and Example 3 is that:
[0060] The tail knot is formed by three relatively dense spring-type structures 52 connected in series in sequence through straight wires 53, wherein the three relatively dense spring-type structures 52 have the same density.
[0061] Embodiment 5:
[0062] like Figure 5 As shown, the difference between Example 5 and Example 4 is that:
[0063] The tail hook is formed by two up-and-down stacked two-ring twisted eight-shaped structures 54 connected in series.
[0064] Embodiment 6:
[0065] like Figure 6 As shown, the difference between Example 6 and Example 5 is:
[0066] The tail knot is a three-ring twisted eight-shaped structure 54.
[0067] Embodiment 7:
[0068] like Figure 7 As shown, the difference between Example 7 and Example 6 is that:
[0069] The tail knot is a petal-shaped structure formed by connecting a plurality of arc-shaped structures 55 in series.
[0070] In the above embodiment, the diameter of the pulling wire is less than 2 mm.
[0071] The present invention further provides an integrated retractor, which differs from the above-mentioned integrated retractor suturing device in that it does not include a suturing needle 2 .
[0072] The present invention further provides an integrated pulling puncture device, comprising the above-mentioned integrated pulling device and a puncture needle 3 ; one end of the integrated pulling device is arranged inside the puncture needle 3 .
[0073] The method of using the integrated retractor of the present invention is as follows:
[0074] Step 1: If Figure 8 and Fig. 9 As shown, the end of the head pulling rope 11 of the retractor without a sutured needle 2 away from the tail knot is inserted into the hollow puncture needle 3. Due to its material characteristics, the tail knot can be deformed under external force and enter the hollow puncture needle 3. The length of the retractor is longer than the puncture needle 3. After the assembly is completed, the head pulling rope 11 of the retractor will be exposed from the tail of the puncture needle 3, which is convenient for the operator to pull;
[0075] Step 2: If Fig.10As shown, when the puncture needle 3 enters the body and reaches above the target tissue 6 / organ to be pulled, a suitable pulling position is selected, and the tissue 6 / organ is pierced so that the needle tip of the puncture needle 3 is exposed from the other end of the tissue 6 / organ;
[0076] Step 3: If Fig.11 and Fig.12 As shown, the knot at the end of the retractor is pushed out from the needle head of the puncture needle 3, and the knot at the end of the retractor is freed from the restraint of the tube wall of the puncture needle 3, and with the help of the memory property of its material, it will automatically form a corresponding knot shape;
[0077] Step 4: Fig.13 and Fig.14 As shown, the puncture needle 3 is withdrawn, the head traction rope 11 of the retractor is pulled up, and the tail is hung on the other end of the tissue 6 / organ to form a block to achieve traction;
[0078] Step 5: Fig.15 As shown, if the Figure 2 The head pulling rope 11 shown has an S-shaped structure 4 part. After the tail knot is released, the S-shaped structure 4 part of the head pulling rope 11 can be pulled by the puncture needle 3 to hang on the spring of the tail knot to trap and lock the tissue 6.
[0079] like Fig.16 , Fig.17 and Fig.18 As shown, the integrated traction suture device of the present invention uses a suture needle 2 to penetrate the target tissue 6 / organ for traction, and the knotted part at the tail of the traction device forms a barrier at the insertion end of the suture needle 2 to achieve traction.
