Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely is a kind of incision protective sleeve for thyroid surgery. BACKGROUND

[0002] In thyroid surgery, incision protection is a crucial link. Traditional incision protection measures often have problems such as insufficient fixation and poor adaptability, making it difficult to meet the needs of different surgical sites and incision sizes. The incision protection sleeves on the market are usually of several different sizes, which need to be selected according to the size of the incision, and the size and price vary.

[0003] Chinese patent document CN 212879415U discloses a surgical protection sleeve with adjustable diameter, which introduces in the background art section: Since the surgical protection sleeve has a fixed size, it is not ideal for different individuals during surgery. When the incision needs to be temporarily enlarged during surgery, a surgical protection sleeve of a different size needs to be replaced to adapt. Its adjustment method is: an insurance buckle is arranged at the ends of the first connecting ring, the first connecting ring is inserted into the adjusting ring to form a threaded adjustable connection, and the buckle head of the insurance buckle is placed in the locking groove. The purpose of adjustable diameter is achieved by moving the position of the buckle head. The disadvantage is that the structure is relatively complex and the manufacturing cost is high.

[0004] Chinese patent document CN221383808U discloses a simple incision protection structure, the main body of which is an elastic protection sheet with an arc-shaped cross-section. The elastic protection sheet has a buckle and multiple card holes at both ends. After the buckle and the card hole are connected, the elastic protection sheet forms a ring-shaped cylinder, and the ring-shaped cylinder defines an operation channel. This incision protection structure can adjust the ring-shaped cylinder according to the size of the incision during surgery, so that it can adapt to incisions of various sizes. However, its disadvantage is that the aperture of the ring-shaped cylinder formed by the elastic protection sheet can only be determined by the distance between the card holes, and cannot be continuously adjusted. In other words, this solution needs to adapt to the incision protection structure from the incision, which is contrary to the main and subordinate relationship.

[0005] It should be noted that the incision protection structure disclosed in Chinese patent document CN221383808U is only suitable for thyroid surgery, and its supporting force cannot meet the supporting force required for laparotomy surgery. The retractor used in laparotomy surgery needs to be pulled open with great force to achieve full exposure.

[0006] In another aspect, in order to make the incision protective sleeve better adapt to the incision, the Chinese patent document CN219516574U discloses a thickness-adjustable incision protective sleeve device, which is directed to the fixed distance between the insertion ring and the outer ring of the existing incision protective sleeve, which causes it to not be well adapted to the different thicknesses of human abdominal tissues. It is proposed that the support ring and the incision protective sleeve are separately arranged, and the axial length of the incision protective sleeve is adjusted by turning over the upper ring or the lower ring of the incision protective sleeve, so that it can be adapted to the thicknesses of different human abdomens. For thyroid surgery, the same technical problem also exists. Utility model content

[0007] The utility model discloses a kind of incision protective sleeves for thyroid surgery, and the elastic strip body can form annular cylinder body strictly corresponding to the size of incision using simple structure.

[0008] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0009] The incision protective sleeve for thyroid surgery is made of elastic strip material with circular arc cross section, and connecting structure and cooperating structure are respectively arranged at both ends. When the two ends are connected, a circular cylinder is formed. The connecting structure is two parallel through holes, and the cooperating structure is two parallel axial through grooves. When the two ends of the protective sleeve are aligned, the two through holes are located inside the two axial through grooves.

[0010] The invention concept of the present application is to improve the connecting structure and the cooperating structure in Chinese patent document CN221383808U. The incision protective sleeve of the present application requires the cooperation of surgical silk and scissors. Before use, a piece of surgical silk is threaded through the axial through groove and the through hole respectively. The surgical silk in the through hole is then threaded through the axial through groove. After the ends of the two pieces of surgical silk are knotted, two nooses are formed, which are convenient for pulling in opposite directions. After the incision protective sleeve is inserted into the incision, one person pulls the two nooses to make the annular cylinder correspond to the size of the incision, and the other person cuts a clasp on the side of the axial through groove. By clamping the noose at the end of the connecting structure into the clasp, the fixation of the connecting structure and the cooperating structure can be achieved. To prevent the noose at the end of the connecting structure from coming out of the clasp, a slipknot can be tied to prevent the noose at the end of the connecting structure from coming out of the clasp.

[0011] Secondly, when the opening needs to be expanded, the noose at the end of the connecting structure is pulled out of the clasp, and the two nooses are further stretched in opposite directions. After stretching to the limit, a cut is made at the corresponding position of the axial through groove. After the noose at the end of the connecting structure is clamped into the clasp, secondary fixation is achieved.

[0012] As an improvement, the length of the incision protective sleeve is 20-25 cm.

[0013] As an improvement, the length of the through groove is 5-10 cm.

[0014] As an improvement, the gap between the through-slots is at least 0.5 cm.

[0015] As a further improvement, the incision protection sleeve is provided with axial indication lines along its edge, the axial indication lines being 0.3-0.6 cm away from its edge.

[0016] As a still further improvement, the number of the axial indication lines is two, the two axial indication lines being 0.3-0.6 cm apart.

[0017] In summary, the utility model adopts simple structure, cooperates surgical silk and scissors, can form the annular cylinder which strictly corresponds to the incision size, the circle diameter is continuously adjustable, not only low production cost, but also convenient to use, has the expanding function, helps to improve the operation adaptability.

[0024] The utility model will be further described in combination with specific embodiments. It should be understood that these embodiments are only used for illustrating the utility model and are not used for limiting the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0025] Embodiment 1

[0026] As Figure 1As shown, the incision protective sleeve for thyroid surgery described in this solution differs mainly from the technical solution disclosed in Chinese patent document CN221383808U in the difference between the connecting structure 10 and the mating structure 20. The incision protective sleeve of this application is also made of an elastic strip material with a circular arc cross-section, with a length of 22cm, and connecting structures 10 and mating structures 20 are respectively provided at both ends, forming a circular cylinder after the two ends are connected.

[0027] In this application, the connecting structure 10 consists of two parallel through holes, and the mating structure 20 consists of two parallel axial through grooves. The length of the axial through groove is 5 cm. Obviously, the longer the axial through groove, the greater the adjustment range of the ring diameter. Preferably, the length of the through groove is 5-10 cm. Secondly, there needs to be a certain gap between the axial through grooves, which is at least 0.5 cm to facilitate the formation of a cut 40 with scissors. In this embodiment, it is preferably 0.8 cm. When the two ends of the protective sleeve are aligned, the end with the through hole is located inside the other end, the two through holes are located inside the two axial through grooves, and the distance between the two through holes is 0.4 cm.

[0028] like Figure 1 As shown, at the beginning of use, take two surgical sutures 50 and pass them through the axial groove and through hole respectively. The surgical suture 50 in the through hole is then passed through the axial groove again. The ends of the two surgical sutures are tied to form two loops for easy pulling in opposite directions. Next, put the incision protector on the surgical incision and pull the two loops until the formed annular cylinder corresponds to the size of the surgical incision. After pulling it in place, the assistant uses scissors to cut a notch 40 on the side of the axial groove. The loop corresponding to the through hole can then be inserted into the notch 40 for fixation. Specifically, as shown... Figure 2 As shown. To prevent the snare from accidentally slipping out of the latch 40, a slip knot can be tied to prevent the snare from coming off the latch. When widening is needed, pull the snare out of the latch 40, hold both snares and continue to pull them towards each other until they are stretched to their limit. Then, cut a slit 40 at the corresponding position in the axial through groove, and insert the snare into the new latch 40 to achieve secondary fixation. See details below. Figures 3-4 As shown. Among them, Figure 4 The image shows a slip knot that has not yet been tightened. Tying a slip knot with a piece of thread is common sense, so the specific method will not be elaborated further. As long as the slip knot is not untied, the snare will not slip out of the 40° opening, ensuring the connection is secure.

[0029] Example 2

[0030] like Figure 5As shown, the difference between this embodiment and Embodiment 1 is that: two rows of axial indicator lines 30 are set parallel to the edge of the incision protective sleeve, with the axial indicator lines 30 0.4cm away from the edge and the two axial indicator lines 30 also 0.4cm apart. In use, if the thickness of the surgical incision is reduced, part of the incision protective sleeve can be removed beforehand along the axial indicator lines 30 with scissors to better correspond to the thickness of the surgical incision.
