A plurality of branch pipe bodies are arranged on the rear portion of the foreign matter containing section, namely an inner cavity of the main pipe body. According to the foreign matter taking-out tube, various problems existing in a foreign matter taking-out tube in the prior art are solved, on the premise that multiple channels are matched with multiple instruments for synchronous operation, compared with the prior art, the outer diameter capable of containing the foreign matter is increased, particularly, the flexible rubber sleeve can be released to continue to wrap the foreign matter in the foreign matter taking-out process, and damage caused by taking out of the foreign matter is further avoided.

Description

Technical Field

[0001] The utility model relates to the field of surgical instruments, in particular to a foreign body removal tube for endoscope. Background Art

[0002] Gastrointestinal endoscopy often involves foreign body removal operations. Since the edges and corners of some foreign bodies are not smooth, it is easy to cause secondary damage to the patient during the removal process. To solve the above problems, such as the foreign body removal device for endoscopy disclosed in Chinese Patent 202022645714.1, although the device can wrap foreign bodies to a certain extent and prevent foreign bodies from falling, its setting form is also unreasonable, especially because the device has a single tube mouth and cannot integrate laparoscope equipment, that is, the operation process will cause more wounds; another example is a pneumatic soft shell for assisting endoscopic foreign body removal disclosed in Chinese Patent 202210868774.0. Although the device has multiple cavities in a single tube, the device has a complex structure, high requirements for operation conditions, and cumbersome operation. In addition, the space for accommodating foreign bodies is only a single cavity in the shell capsule, that is, the tube body entering the body is large, but the foreign bodies that can be removed are limited by the single cavity. There is currently a lack of specific solutions to the above problems. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an endoscopic foreign body removal tube that has a more reasonable setting, can better protect the foreign body removal process from causing secondary trauma to the human body, can accommodate foreign bodies with a larger outer diameter, has lower requirements for surgical conditions, and is more convenient to operate.

[0004] The device comprises a main body, which is the assembly basis of the device; a foreign body receiving section is arranged at the front of the main body; and a plurality of branch pipes are arranged at the rear of the foreign body receiving section, that is, in the inner cavity of the main body.

[0005] The effect achieved in this way is that the multiple branch tubes can be used synchronously with surgical instruments such as an endoscope, biopsy forceps and foreign body forceps; and the multiple branch tubes are arranged at the rear of one end of the main tube, and the foreign body receiving section can be used as the foreign body receiving section with the maximum inner diameter of the main tube.

[0006] The beneficial effects of the utility model are as follows: the utility model solves various problems existing in foreign body removal tubes in the prior art, and under the premise of multi-channel and multi-instrument synchronous operation, the outer diameter that can accommodate foreign bodies is increased compared with the prior art, especially the flexible rubber sleeve can be released during the foreign body removal process to continue to wrap the foreign body, further avoiding damage during foreign body removal.

[0015] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0016] Reference Figure 1 , Figure 2 The utility model discloses an endoscope foreign body removal tube, comprising a main body 1, which is the assembly basis of the device; a foreign body receiving section 11 is arranged at the front of the main body 1; and a plurality of branch tubes are arranged at the rear of the foreign body receiving section 11, that is, in the inner cavity of the main body 1.

[0017] Preferably, the main pipe 1 is made of silicone.

[0018] The effect achieved in this way is that the multiple branch tubes can be used synchronously with surgical instruments such as an endoscope, a biopsy forceps, and a foreign body forceps; and the multiple branch tubes are arranged at the rear part of one end of the main tube 1, and the foreign body receiving section 11 can be used as the foreign body receiving section 11 with the maximum inner diameter of the main tube 1.

[0019] Furthermore, there are three branch pipe bodies in total, including a laparoscope pipe 2 with the largest inner diameter and an instrument pipe 3 with a smaller inner diameter than the laparoscope pipe 2;

[0020] A flexible filler is arranged between the branch pipe bodies, thereby preventing the pipes from being entangled in the main pipe body 1.

[0021] Embodiment 1: Refer to the accompanying drawings of the specification Figure 4The front end of the main pipe body 1 is provided with a positioning ring 12 on its outer ring surface.

[0022] The effect achieved by this is that, specifically in clinical surgery, the rubber sleeve 13 will be rolled into a ring and put on the foreign body removal tube. When the tube is pulled out, the rubber sleeve 13 ring is automatically released to further protect the foreign body and prevent secondary damage.

[0023] Embodiment 2: Refer to the attached drawings of the specification Figure 5 The front end of the main body 1 is provided with a rubber sleeve 13, which is a rubber ring formed by rolling a thin rubber sleeve 13, and its rolling direction is inward. That is, when the main body 1 is pulled out, the rubber sleeve 13 is automatically released downward to wrap the foreign matter.

[0024] Furthermore, the main pipe 1 is provided with various lengths and outer diameters.

[0025] Furthermore, the outside of the main tube 1 is provided with scale marks.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
