Description

Technical Field

[0001] This utility model relates to an incision protective sleeve, and more particularly to a novel incision protective sleeve for use in laparoscopy. Background Technology

[0002] In recent years, with the rapid development of minimally invasive surgical techniques, thoracoscopic surgery has gradually become one of the important surgical methods in the field of surgery and is widely used in complex surgeries such as lung cancer resection. Compared with traditional open surgery, minimally invasive surgery has advantages such as less trauma, faster recovery, and smaller postoperative scars, and can significantly reduce intraoperative risks and improve the speed of postoperative recovery for patients. However, the operating environment for thoracoscopic surgery is relatively limited, especially when complex surgical procedures need to be performed through a single operating port with a diameter of only 3 centimeters. Maintaining the surgical field and the smooth use of instruments become the main challenges faced by surgeons.

[0003] Currently, the incision protectors commonly used in thoracoscopic surgery are usually simple ring-shaped structures. They are mainly used to reduce mechanical friction on the tissues at the incision edge during surgery, providing a certain degree of protection. In addition, they provide some support for surgical instruments such as the thoracoscope when the surgical assistant holds them.

[0004] However, with traditional incision protectors, surgical assistants must hold instruments such as thoracoscopes for extended periods to maintain a clear surgical field. This prolonged fixed posture can lead to fatigue, increase the workload during surgery, and potentially reduce surgical precision and outcome. Therefore, there is an urgent need for a novel incision protector to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a novel incision protective sleeve that assists in the stable operation of surgical instruments during long-term procedures.

[0013] Preferably, the sleeve has a receiving groove, and the opening of the sleeve has a communicating groove that communicates with the receiving groove.

[0014] The limiting member is disposed in the receiving groove, and the portion of the limiting member opposite to the connecting groove is exposed through the connecting groove. The side of the limiting member facing the connecting groove and the inner wall of the connecting groove form the limiting space.

[0015] Preferably, the limiting member is an elastic member.

[0016] Preferably, the receiving groove is an annular groove, the limiting member is an annular member, and the limiting member is an elastic member.

[0017] Preferably, the number of the receiving slots is at least three, and at least two of the receiving slots are arranged symmetrically.

[0018] Preferably, the opening of the receiving groove is circular or square, and the radius or size of the receiving groove is any value from 1 to 1.5.

[0019] Preferably, the opening of the sleeve is an elastic ring, and the surface of the sleeve is provided with a protective film.

[0029] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] The novel incision protective sleeve 100 proposed in this application aims to provide support and limiting space 113 for operating instruments, thoracoscopes and suction devices during surgery, so as to restrict the instruments within a specific range, ensure stable operation of the instruments, and avoid interference between different instruments.

[0033] See Figure 1-5 A preferred embodiment of this application provides a novel incision protector 100, comprising a sleeve body 110, the sleeve body 110 including an accommodating space 111, and at least two openings 112 communicating with the accommodating space 111. A limiting space 113 is provided at each opening 112 to accommodate the gripping portion of a surgical instrument when the incision protector 100 is in working condition, and to ensure an interference fit between the gripping portion of the surgical instrument and the limiting space 113, thereby increasing the frictional resistance of the surgical instrument. This novel incision protector 100, by employing the technique of providing a limiting space 113 at the opening 112 of the sleeve body 110, effectively increases the frictional resistance of the surgical instrument by creating an interference fit between the gripping portion of the surgical instrument and the limiting space 113. Figure 4As shown. Therefore, it effectively solves the problems of unstable fixation of surgical instruments and potential mutual interference during operation in the prior art, further realizes the stability of surgical instruments during operation, reduces the labor intensity of surgical assistants, reduces the risk of decreased surgical precision due to fatigue, and improves the operation efficiency and safety of minimally invasive surgery.

[0034] The sheath 110 has a tubular overall shape, with the interior space serving as the accommodating space 111. Both ends of the tube have two openings 112 communicating with the accommodating space 111. During surgery, the sheath 110 passes through an incision in the cavity to expand the incision and provide operational space. The cross-sectional shape of the sheath 110 can be circular, elliptical, or other irregular shapes. In this embodiment, a circular cross-sectional shape is used as an example. A circular cross-sectional shape allows for more even stress distribution when bearing pressure from the incision edge, providing dual protection for both the sheath 110 itself and the incision. Specifically... Figure 1 As shown.

[0035] The limiting space 113 is a slot located at the opening 112, through which the grip handle and other parts of the surgical instrument pass. The inner wall of the slot abuts against the surface of the grip part after the surgical instrument passes through the slot, thereby limiting the relative movement range between the surgical instrument and the sheath 110. It should be noted that the limiting space 113 may be located at only one opening 112, or it may be provided at each opening 112.

[0036] In some embodiments, the novel cut-out protective sleeve 100 further includes a limiting member 120, which is disposed at the opening 112 of the sleeve body 120. The limiting member 120 and the side of the sleeve body 110 facing the sleeve body 110 together with the side of the opening 112 of the sleeve body 110 facing the limiting member 110 form the limiting space 113.

[0037] The limiting member 120 should include at least a first plane so that the sides of the opening 112 can surround and form a limiting space 113. In this embodiment, the shape of the limiting member 120 includes linear and strip-shaped shapes, etc.

[0038] Furthermore, in some embodiments, in order to ensure the fit between the inner wall of the limiting space 113 and the surface of the surgical instrument grip, and to ensure that the surgical instrument can move within a certain range, the limiting member 120 may be an elastic member, including rubber rope, etc.

[0039] It should be noted that the limiting component 120 can also be a rigid component, and the specific form of the limiting component 120 can be determined according to the actual application scenario.

[0040] In one embodiment, the novel cut-out protective sleeve 100 further includes a first connecting portion (not shown in the figure) and a second connecting portion (not shown in the figure). The first connecting portion is disposed at the end of the limiting member 120, and the second connecting portion is disposed at the opening 112 on the sleeve body 110. The first connecting portion and the second connecting portion are detachably connected.

[0041] The first connecting part and the second connecting part can be selected as a snap-fit ​​connection. Each end of the limiting member 120 can be provided with a first connection, or the first connecting part can be installed only at one end of the limiting member 120. The other end of the limiting member 120 is directly connected to the opening 112 of the sleeve 110. The connection relationship between the two can be selected as a fixed connection or a rotating connection depending on the material of the limiting member 120. When the limiting member 120 is an elastic member, the connection relationship between one end of the limiting member 120 and the opening 112 of the sleeve 110 can be a fixed connection. When the limiting member 120 is a rigid member, a rotating connection, such as a hinge, can be used.

[0042] The number of the second connecting parts is the same as the number of the first connecting parts, so that the first connecting parts and the second connecting parts are matched in equal quantities, so that the limiting member 120 can be connected to the opening 112 of the sleeve 110, thereby forming the limiting space 113.

[0043] In another embodiment, both ends of the limiting member 120 are connected to the sidewall of the opening 112 on the sleeve 110, that is, both ends of the limiting member 120 are fixedly connected to the opening 112 on the sleeve 110, and the connection between the two includes bonding and integral molding.

[0044] In another embodiment, the sleeve 110 is further provided with a receiving groove 140 near the opening 112, and a communicating groove 150 communicating with the receiving groove 140 is provided at the opening 112 of the sleeve 110. The limiting member 120 is disposed in the receiving groove 140, and the opposite part of the limiting member 120 and the communicating groove 150 is exposed through the communicating groove 150. The side of the limiting member 120 facing the communicating groove 150 and the inner wall of the communicating groove 150 together form the limiting space 113.

[0045] Among them, the limiting member 120 is partially exposed under the action of the connecting groove 150, and there is a gap between the exposed part and the inner wall of the receiving groove 140. This gap is the limiting space 113. When the limiting member 120 is an elastic member, the size of the gap can change with the size of the gripping part of the surgical instrument.

[0046] Furthermore, in some embodiments, the receiving groove 140 is an annular groove, the limiting member 120 is an annular member, and the limiting member 120 is an elastic member, with the annular member movably located within the annular groove, specifically as follows: Figures 3 to 5 As shown.

[0047] When the new incision protector 100 is in operation, the portion of the annular member exposed outside the receiving groove 140 through the connecting groove 150 can be pulled open to allow surgical instruments to pass through. After the surgical instruments are positioned as required, the exposed portion of the annular member can be released to clamp the gripping part of the surgical instruments.

[0048] Furthermore, the number of receiving slots 140 is at least three, and at least two of the receiving slots 140 are symmetrically arranged, so that there are at least three limiting spaces 113, and at least two limiting spaces 113 are symmetrically arranged. Therefore, after the thoracoscope is inserted into and fixed in one limiting space 113, when smoke needs to be aspirated in the surgical field, the limiting space 113 symmetrical to the limiting space 113 used to fix the thoracoscope can be used to pull out the limiting member 120 to fix the suction device. The fixing of other surgical instruments can also be done in the same way, using the remaining limiting spaces 113 in conjunction with the limiting member 120 for fixation, to ensure sufficient operating space within a single surgical port. Specifically, as shown... Figures 4 to 5 As shown.

[0049] In some embodiments, when the limiting member 120 is an elastic member, its material is natural rubber.

[0050] In some embodiments, the groove shape of the receiving groove 140 is circular or square, and the radius or size of the receiving groove 140 is any value from 1 to 1.5. With the cooperation of the shape and size of the receiving groove 140, the limiting member 120 of the elastic member can be pulled out smoothly, so as to improve the operability of the new cut protective sleeve 100.

[0051] In some embodiments, the opening 112 of the sleeve 110 is an elastic ring, and the surface of the sleeve 110 is provided with a protective film.

[0052] The elastic ring can be connected to the sleeve 110 in two ways: integral molding and fixed connection. Setting the opening 112 of the sleeve 110 as an elastic ring ensures that when the grip part of the surgical instrument is inserted into the limiting space 113 and has an interference fit with the limiting space 113, the inner sidewall of the limiting space 113 has a better fit with the surface of the grip part of the surgical instrument, so as to ensure better stability between the surgical instrument and the limiting space 113. In this embodiment, the elastic ring is preferably medical silicone. When the elastic ring is integrally molded with the sleeve 110, the material of the sleeve 110 is the same as that of the elastic ring.

[0053] The protective film, made of polyurethane, is typically located on the outer surface of the sheath 110 and is designed to isolate the patient's incision tissue. In some embodiments, a protective film may also be provided on the inner surface of the sheath 110.

[0054] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
