Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a tracing device for guiding an intestinal tube for stoma during surgery. Background Art

[0002] Conventional stoma is caused by digestive system diseases and requires surgical treatment to separate the intestine and lead one end of the intestine to the body surface (the anus is moved to the abdominal wall) to form an opening.

[0003] However, patients with stomas are prone to parastomal hernias and need parastomal hernia repair, of which laparoscopic parastomal hernia repair is currently a more common repair method in clinical practice. However, due to previous surgical history, the greater omentum, intestine and its mesentery in the patient's abdominal cavity usually form extensive adhesions with the stoma intestine and the surrounding abdominal wall, making the stoma intestine difficult to identify during laparoscopic parastomal hernia repair, and the risk of injury is high. Summary of the invention

[0004] The purpose of the present invention is to provide a stoma intestinal tube guiding and tracing device for intraoperative stoma intestinal tube indication and auxiliary traction, thereby solving the problem of difficult identification and easy damage of the stoma intestinal tube during laparoscopic parastomal hernia repair.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The present invention provides a tracing device for guiding an intestinal tube for stoma during surgery, comprising a flexible transparent column, a push switch arranged in the flexible transparent column, a wireless charger, a battery, a plurality of tracing lights, and a plurality of optical fibers;

[0007] The push switch is embedded in an integrated silicone shell and is responsible for controlling the device light; the battery is connected to the wireless charger; a plurality of tracing lights are electrically connected to the battery via wires; and each tracing light is respectively connected to one of the optical fibers.

[0008] Furthermore, the material of the flexible transparent cylinder is medical grade silicone.

[0009] Furthermore, the Shore hardness of the flexible transparent cylinder is A60, which can ensure good supporting force while avoiding damage to the intestinal mucosa. During the operation, this device can be used to "pick" the stoma intestinal tube in different directions to assist in pulling the intestinal tube.

[0010] Furthermore, the tracer light is a low-intensity red light LED.

[0011] Furthermore, one end of the optical fiber is connected to the tracer light, wherein the optical fiber surrounds the center of the flexible transparent cylinder and is arranged in a spiral; the optical fiber is a plastic optical fiber.

[0012] Furthermore, the battery is a lithium-ion battery.

[0013] Furthermore, a multivibrator for controlling the flashing frequency of the light is arranged on the tracer light.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are:

[0015] In the present invention, a red light lamp and an optical fiber are installed in a flexible transparent column, and periodic flashing is set to facilitate intestinal tracing during surgery; the flexible transparent column is medical-grade silicone with a Shore hardness of A60, which ensures good support and moderate elasticity while avoiding damage to the intestinal mucosa; in addition, the lamp power supply of the present application is the same as the wireless charging technology to avoid gaps, thereby ensuring the waterproof effect of the overall structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] Figure 1 It is a main schematic diagram of the stoma intestinal tube guiding tracing device used during surgery of the present invention.

[0018] Explanation of reference numerals: 100, flexible transparent cylinder; 200, optical fiber; 300, tracer light; 301, wire; 400, battery; 500, wireless charger; 600, push switch. DETAILED DESCRIPTION

[0019] like Figure 1 As shown, the present embodiment discloses a tracing device for guiding an intraoperative stoma intestinal tube, comprising a flexible transparent cylinder 100, a push switch 600 installed in the flexible transparent cylinder 100, a wireless charger 500, a battery 400, five groups of tracing lights 300, and five optical fibers 200; wherein the battery 400 is connected to the wireless charger 500; a plurality of the tracing lights 300 are electrically connected to the battery 400 via a wire 301; and each of the tracing lights 300 is respectively connected to one of the optical fibers 200.

[0020] In this embodiment, the material of the flexible transparent column 1 is medical grade silicone, wherein the medical grade silicone is semi-transparent; and the Shore hardness of the flexible transparent column 1 is A60; while ensuring elasticity and flexibility, the hardness requirements are met, ensuring that the device can play a supporting, guiding and pulling role during use without damaging the intestinal mucosa.

[0021] In this embodiment, the tracing light 300 is a low-intensity red light LED with a wavelength of 620-750nm; it has good tissue penetration ability, and red light can be observed through the intestinal wall of the stoma, which is helpful for laparoscopic intestinal tract tracing. The push switch 600 is embedded in the integrated silicone shell and is used to control the tracing light 300.

[0022] In this embodiment, one end of the optical fiber 200 is connected to the tracing light 300, wherein the optical fiber 200 surrounds the center of the flexible transparent cylinder 100 and is arranged in a spiral; the optical fiber 200 is a plastic optical fiber. Five pairs of low-intensity red light LEDs and the plastic optical fiber arranged in a spiral around the center transmit red light to the entire flexible transparent cylinder 100, and the light-scattering properties of the translucent silicone (flexible transparent cylinder 100) make the entire device evenly scatter red light outward to achieve a tracing effect.

[0023] In this embodiment, a 1000mAh lithium-ion battery is used as the battery 400. Considering that the device is not a disposable device and needs to be disinfected after each use, and the working environment is a humid environment, in order to ensure a good waterproof effect, the device adopts wireless charging technology, specifically using a wireless charger 500, and specifically using the principle of an induction coil.

[0024] In this embodiment, a multivibrator for controlling the flashing frequency of the light is installed on the tracer light 300; when in use, a switching cycle combining high-frequency flashing and lower frequency is adopted, that is, flashing 100 times per second (100Hz), opening and closing once (1Hz) or twice (2Hz) per second, so as to achieve a better prompting effect and avoid visual fatigue.

[0025] The above embodiments are only descriptions of the preferred methods of the invention, and are not intended to limit the scope of the invention. Without departing from the design spirit of the invention, various modifications and improvements made to the technical solutions of the invention by ordinary technicians in this field should fall within the protection scope of the claims of the invention.
