Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an isolation and traction device for laparoscopic surgery. Background Art

[0002] At present, laparoscopic surgery is becoming increasingly important as a mainstream technology in the field of abdominal surgery. However, the successful implementation of this operation is highly dependent on good exposure of the surgical field. In the process of establishing pneumoperitoneum, a key challenge is how to effectively deal with the increasing number of obese patients. Because obese patients have dense intestinal tracts and abundant adipose tissue in the abdominal cavity, this greatly hinders the clear display of the surgical field, thereby increasing the complexity and risk of surgical operations.

[0003] Faced with this dilemma, clinicians often encounter operational difficulties during laparoscopic surgery, and sometimes even have to abandon laparoscopic technology and switch to traditional open surgery. This shift not only prolongs the operation time, but also increases the patient's physical trauma and difficulty in postoperative recovery, causing greater pain to the patient. Therefore, how to optimize the exposure of the surgical field during laparoscopic surgery and how to effectively block the interference of the intestinal tract have become a big problem.

[0004] Currently, there are corresponding instruments that can block and isolate the intestinal tubes to assist in exposure; they can also expose the field of view to a certain extent; however, current instruments generally directly clamp up a single intestinal tube and then pull it apart to expose the surgical field of view. At the same time, current instruments need to use multiple instruments to pull and expose different intestinal tubes to obtain the surgical field of view; although the surgical field of view is obtained to a certain extent, the relative field of view will become narrower as the number of instruments increases, and the presence of multiple instruments will not meet the surgical operating space well; in addition, the intestinal tubes are generally stacked and entangled with each other, and a single clamp can easily cause other intestinal tubes to slip and block the surgical field of view; there are still defects to a certain extent.

[0005] Therefore, a laparoscopic surgery isolation and traction device is needed to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION Example 1

[0011] The present invention discloses a laparoscopic surgical isolation and traction device, comprising: a laparoscope support 1, an execution sleeve 2, a release rod 3, and a support assembly 4; the front end of the laparoscope support 1 is movably connected to the execution sleeve 2, and a through hole 14 is axially opened on the laparoscope support 1, and the release rod 3 is rotatably connected to the through hole 14 by a thread, and the front end of the release rod 3 is fixedly installed with the support assembly 4; through the cooperation between the support assembly 4 and the release rod 3, the support rod 44 installed on the support assembly 4 can be expanded outward, and after the expansion, the intestinal tube around the surgical site can be blocked and opened; in addition, a support membrane 45 is fixedly installed on the support rod 44, and the setting of the support membrane 45 can make the front end of the support assembly 4 unfold into an umbrella-like structure, so that it can better open the intestinal tube, and at the same time, the opening angle of the support rod 44 can be controlled by the release rod 3, that is, the opening size of the support rod 44 can be controlled according to actual needs to better meet the needs of the operation; Specifically, the support assembly 4 includes: a support sleeve 42 and a support rod 44. A plurality of the support rods 44 are movably installed in a circular array on the front periphery of the support sleeve 42 through a rotating shaft 43. A torsion spring is movably installed on the rotating shaft 43 to control the support rod 44 to continuously open outward. At the same time, the torsion spring can also be equivalently replaced by a material that can be reset. A support film 45 is fixedly connected to the outer side of the support rod 44, and the support film 45 is closed. The opening or closing of the support rod 44 is controlled by controlling the forward and backward movement of the release rod 3 to support the intestinal tube. The support film 45 is a medical isolation film. The medical isolation film can be made of a polytetrachloroethylene film or a mesh-structured plastic film or a soft metal film. The intestinal tube can be directly blocked by the support film 45, and it is not targeted at a single intestinal tube, but nearby intestinal tubes can be blocked. At the same time, in this embodiment, an extension block 441 is extended from the front end of the support rod 44, and the front end of the extension block 441 is bent inwardly, and the material of the extension block 441 is soft silicone material; the extension block 441 at the front end of the support rod 44 is bent inwardly, and when in use, the part to be operated on can be directly wrapped by the umbrella-like structure, which can form a good support; although the inwardly bent structure can directly block the intestinal tract outside when blocking the intestinal tract, once the opening angle of the support rod 44 is changed, the intestinal tract will immediately enter the surgical field of view; it has certain defects, but it can still be used as one of the methods.

[0012] At the same time, in order to better overcome the above-mentioned defects in the present embodiment, the support rod 44 is made of memory metal, and the support rod 44 is bent upward to form a concave structure; that is, after being pushed outward by the release rod 3, the support rod 44 will bend upward once it leaves the support sleeve 42; that is, it bends upward with the support membrane 45 to form a concave structure, and the nearby intestinal tube can be directly supported by the concave structure, which can effectively prevent the intestinal tube from blocking the surgical field of view, and there is no need to worry about the problem that the intestinal tube immediately slips into the surgical field of view after the angle of the support rod 44 changes; this method can effectively overcome the above-mentioned technical problems. Example 2

[0013] In this example, the connection method of the execution sleeve 2 is further described. Specifically, an extension ring 21 is fixedly installed at one end of the execution sleeve 2 close to the laparoscope support 1, and a plurality of second limit blocks 22 are linearly installed in a circular array on the outer wall of the extension ring 21, and the second limit blocks 22 and the execution sleeve 2 are arranged at intervals; a slide groove (not shown in the figure) is provided inside the execution sleeve 2, and the slide groove is provided to prevent the rotation of the support sleeve 42, that is, to effectively prevent the support sleeve 42 from rotating due to the existence of friction during the process of the release sense rotating forward; At the same time, a slider 41 is fixedly installed on the middle outer wall of the support sleeve 42 to cooperate with the support sleeve 42, and the slider 41 and the slide groove cooperate with each other; a groove 47 is provided on the end surface of the support sleeve 42 away from the rotating shaft 43, and a second annular slide groove 471 is provided at the end of the groove 47; the groove 47 and the second annular slide groove 471 are provided to cooperate with the release rod 3, and through the form of mutual rotation, the support sleeve 42 will not rotate while the release rod 3 rotates; at the same time, due to the existence of the above-mentioned slider 41 and the slide groove, it can only move back and forth, and the setting of the second annular slide groove 471 ensures that the release rod 3 can move with the support sleeve 42 during the backward movement, thereby controlling the opening and closing of the support rod 44. Example 3

[0014] In this embodiment, a handle 12 is fixedly installed at the lower end of the outer wall of the laparoscope bracket 1. The handle 12 allows the doctor to directly hold and operate. A plurality of first limit blocks 13 are installed in a path array on the handle 12. The limit blocks provided allow the doctor's fingers to be placed between the first limit blocks 13 to give the doctor a better operating feel. In addition, a first annular limit groove is provided on the side wall of the front end of the laparoscope bracket 1 close to the end face, and the first annular limit groove cooperates with the second limit block 22; In addition, in this embodiment, a rotating handle 31 is fixedly installed at the rear end of the release rod 3, and it is a hollow structure. A switch 32 is fixedly installed on the rotating handle 31. The switch 32 is electrically connected to the lighting lamp 46 arranged at the front end of the support sleeve 42. The electrical connection described here is that the lighting lamp 46 and the switch 32 are connected by a wire; or they are connected by forming a path after the electromagnets attract each other. The implementation method can be achieved between the side walls of each sleeve. This method belongs to the prior art and will not be explained in detail here. The brightness of the lighting lamp 46 and the switch 32 can be controlled by the switch 32; while the intestinal tube is stretched open, the illumination of the lighting lamp 46 can make the surgical field brighter, allowing medical staff to clearly see the internal lesions or surgical sites during laparoscopic operations.
