Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a protective sleeve for an endoscopic suction device. Background Technology

[0002] In laparoscopic surgery, the suction device is a core tool for removing blood, tissue fluid, and fumes from the surgical field. A clear surgical field is indispensable for surgeons to accurately assess the tissue structure of the surgical site and to perform various surgical procedures with precision, such as vascular ligation, tissue separation, and suturing. A suction device generally consists of a suction tube, a handle, and a tip connected to the end of the suction tube. The suction tube delivers the material to be removed, the handle facilitates the surgeon's grip and manipulation, and the tip directly acts on the surgical field for suction.

[0003] The suction device currently in use has a rigid tip, which can easily damage tissue when it comes into direct contact with it during surgery. This damage can not only lead to increased bleeding, reduced clarity of the surgical field, and prolonged operation time, but may also cause postoperative complications such as tissue adhesions and infections, adversely affecting the patient's recovery. Utility Model Content

[0004] The purpose of this invention is to provide a protective sleeve for a laparoscopic suction device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A protective sleeve for a laparoscopic aspirator includes a sleeve body that can be fitted onto a suction tube. The sleeve body includes a proximal end near the aspirator operating handle and a distal end near the tip of the suction tube.

[0010] The aforementioned endoscopic suction device protective sleeve contains a thermosensitive color-changing material dispersed within its body, and the color-changing temperature of the thermosensitive color-changing material is 34-36℃.

[0011] The aforementioned endoscopic suction device protective sleeve includes an annular anti-slip protrusion disposed on the inner wall of the sleeve, wherein there is at least one annular anti-slip protrusion.

[0012] The aforementioned endoscopic suction device protective sleeve includes an inner pad, which is connected to the inner wall of the sleeve and has at least one annular anti-slip protrusion.

[0013] In the above technical solution, the endoscopic aspirator protective sleeve provided by this utility model includes a sleeve body that can be fitted onto the aspirator tube.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, this utility model provides a protective sleeve for a laparoscopic aspirator, including a sleeve body 1 that can be fitted onto the aspirator tube. The sleeve body 1 includes a proximal end 11 near the aspirator operating handle and a distal end 12 near the head end of the aspirator tube. An end sleeve 13 matching the head end is provided on the distal end 12. The end sleeve 13 is provided with a fish mouth-shaped opening 131. An anti-slip restraint 2 is provided inside the proximal end 11. A plurality of longitudinal anti-slip protrusions 14 are provided on the outer surface of the sleeve body 1. The plurality of longitudinal anti-slip protrusions 14 are arranged sequentially at intervals along the circumference of the sleeve body 1.

[0023] Specifically, the sheath 1 and the end sleeve 13 are an integral structure, both made of medical-grade silicone, and are milky white tubular structures. Their length is designed according to needs; preferably, the sheath 1 is 2cm long, ensuring coverage of key parts and the tip of the suction tube without compromising operational flexibility due to excessive length. The sheath 1 has a Shore A hardness of 20A, giving it moderate softness and toughness, preventing hard damage upon contact with tissue while ensuring it is not easily deformed or damaged during use.

[0024] In this embodiment, for ease of description, the two ends of the sleeve 1 are referred to as the proximal end 11 and the distal end 12, respectively. After installation, the end of the sleeve 1 closest to the operating handle of the suction device is the proximal end 11, and the end of the sleeve 1 closest to the tip of the suction tube is the distal end 12. Optionally, the inner diameter of the proximal end 11 of the sleeve 1 is set between 3-8mm. The good elastic deformation ability of medical silicone allows it to fit tightly onto the suction tube of different models of endoscopic suction devices. The proximal end 11 of the sleeve 1 is provided with anti-slip limiting members 2, which are arranged sequentially along the circumference of the inner wall of the sleeve 1. The anti-slip limiting members 2 increase the friction between the sleeve 1 and the suction tube, thereby fixing the sleeve 1 and the suction tube together.

[0025] In this embodiment, the distal end 12 of the sleeve 1 is provided with an end sleeve 13 that matches the tip of the suction tube. The end sleeve 13 is provided with a fish-mouth-shaped opening 131. The size of the opening 131 is set as needed. For example, when the fish-mouth-shaped opening 131 is closed, its major axis is 3mm, its minor axis is 1mm, and the radius of curvature of the opening edge is ≥1.5mm. This makes the opening 131 more gentle when in contact with tissue, effectively reducing friction and damage to the tissue. The outer surface of the sleeve 1 is provided with multiple longitudinal anti-slip protrusions 14. Each longitudinal anti-slip protrusion 14 is arranged along the axial direction of the sleeve 1, and the multiple longitudinal anti-slip protrusions are arranged sequentially and spaced apart along the circumference of the sleeve 1. This enhances the friction when the doctor holds the suction device, providing the doctor with a better operating feel.

[0026] The protective sleeve for the endoscopic aspirator provided by this utility model includes a sleeve body 1 that can be fitted onto the aspirator tube. The distal end 12 of the sleeve body 1 is provided with an end sleeve 13 that matches the tip end. The end sleeve 13 is provided with a fish-mouth-shaped opening 131. The proximal end 11 of the sleeve body 1 is provided with an anti-slip limiting member 2. The outer surface of the sleeve body 1 is provided with multiple longitudinal anti-slip protrusions 14. In this way, during use, the sleeve body 1 is fitted onto the aspirator tube, and the anti-slip limiting member 2 makes the sleeve body 1 and the aspirator tube fixedly connected. During surgical operation, the fish-mouth-shaped opening 131 can flexibly conform to the contour of different tissue parts. Compared with the traditional aspirator tip directly contacting the tissue, its gentler contact method can greatly reduce mechanical damage to the tissue.

[0027] In the preferred embodiment of this utility model, the end sleeve 13 is provided with two circular side holes 132, which are located on opposite sides of the end sleeve 13. When the suction device is working, the two circular side holes 132 attract blood, tissue fluid and other substances from different directions. The diameter of the circular side holes 132 can be set as needed, such as 1-1.5 mm. The edge of the circular side holes 132 is provided with a guide slope extending into the sleeve 1, with an inclination angle of 30°-45°. The guide slope can guide the substances to flow smoothly into the side hole along a specific angle, further improving the suction efficiency and reducing the occurrence of liquid residue or backflow.

[0028] In the embodiments provided by this utility model, preferably, each longitudinal anti-slip protrusion 14 is arranged along the axial direction of the sleeve body 1, and the longitudinal anti-slip protrusions 14 are connected to each other through longitudinal arc-shaped surfaces 141. An annular smooth area 15 is provided in the middle part of the outer surface of the sleeve body 1, and arc-shaped connecting parts 151 are provided on opposite sides of the annular smooth area 15. The arc-shaped connecting parts 151 are connected to the longitudinal arc-shaped surfaces 141 one by one. The dimensions of the longitudinal anti-slip protrusions 14 and the annular smooth area 15 are set as needed. For example, the height of the longitudinal anti-slip protrusions 14 is 0.3-0.5mm, the width is between 0.5-1mm, and the spacing between adjacent protrusions is maintained at 1-2mm. The width of the annular smooth area 15 is 3-5mm, and its surface roughness Ra≤0.8μm is used to assist in adjusting the clamping angle of the endoscopic suture needle. Arc-shaped connecting parts 151 are provided on opposite sides of the annular smooth area 15. The radius of curvature of the arc-shaped connecting parts 151 is ≥2mm. The arc-shaped connecting parts 151 realize the seamless transition between the annular smooth area 15 and the longitudinal anti-slip protrusion 14 area, making the connection between different functional areas of the sleeve 1 smoother and avoiding unevenness caused by changes in surface structure, which would affect the doctor's grip and operation.

[0029] In the embodiments provided by this utility model, preferably, the sleeve 1 contains a thermosensitive color-changing material with a color-changing temperature of 34-36°C. Normal human body temperature is generally around 36-37°C, while the temperature of human blood is typically close to 34-36°C. During laparoscopic surgery, one of the main functions of the suction device is to remove blood from the surgical field. When the suction device protective sleeve comes into contact with human blood, because the blood temperature falls within the color-changing temperature range of the thermosensitive color-changing material, the originally milky-white sleeve 1 will change color, turning into a light red. This color change allows the surgeon to promptly detect whether the suction device has come into contact with blood during the procedure.

[0030] In the embodiments provided by this utility model, preferably, the anti-slip limiting member 2 includes an annular anti-slip protrusion 21 disposed on the inner wall of the sleeve 1, and there is at least one annular anti-slip protrusion 21; the annular anti-slip protrusion 21 is disposed on the inner wall of the sleeve 1 near the suction tube to increase the friction between the sleeve 1 and the suction tube, and the number of annular anti-slip protrusions 21 can be one, two, three or more.

[0031] In another embodiment of this utility model, preferably, the anti-slip limiting member 2 includes an inner pad 22. The material of the inner pad 22 can be the same as that of the sleeve 1. The inner pad 22 is connected to the inner wall of the sleeve 1. At least one annular anti-slip protrusion 21 is provided on the inner pad 22. When there are two, three or more annular anti-slip protrusions 21, the annular anti-slip protrusions 21 are arranged sequentially at intervals along the axial direction of the sleeve 1. An annular opening groove is provided at the proximal end 11 of the sleeve 1. The inner pad 22 is detachably installed in the annular opening groove. When the inner pad 22 is damaged, it can be replaced. The thickness of the annular opening groove is consistent with the thickness of the inner pad 22. Thus, when the inner pad 22 is installed on the annular opening groove, the inner pad 22 is flush with the inner wall of the sleeve 1, and the annular anti-slip protrusion 21 extends out and can make abutting contact with the suction tube, so that the sleeve 1 is firmly fitted on the suction tube.

[0032] In another embodiment of this utility model, preferably, an annular mounting member 221 is provided on the outer wall of the inner pad 22. The annular mounting member 221 and the annular anti-slip protrusion 21 are concentrically arranged, that is, the annular mounting member 221 and the annular anti-slip protrusion 21 are respectively arranged on opposite sides of the inner pad 22. An annular mounting groove 23 is provided on the inner wall of the annular opening groove. The annular mounting member 221 can be embedded in the annular mounting groove 23. A plurality of radial elastic columns 24 are also provided in the annular mounting groove 23. The plurality of radial elastic columns 24 are arranged sequentially at intervals along the circumference of the annular mounting groove 23. When the annular mounting member 221 is embedded in the annular mounting groove 23, the elastic columns contact the annular mounting member 221. Thus, the elastic columns provide radial elastic force to the annular mounting member 221. The elastic columns play an elastic buffering role for the annular mounting member 221, the inner pad 22, and the annular anti-slip protrusion 21.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
