Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a double-cover endoscopic biopsy cap. Background Art

[0002] With the continuous development of non-invasive medical technology, from some simple specimen biopsies in the past to the current sophisticated and complex surgical operations, the surgical wounds of patients are significantly reduced and the recovery time of patients is shortened. These minimally invasive operations are all completed under endoscopy, and the operations and operations of digestive endoscopy are all performed through the endoscopic biopsy channel. The success or failure of the operation depends on the integrity of the exposure of the surgical wound, so the airtightness of the endoscopic biopsy cap is very important, which determines the integrity of the exposure of the surgical wound.

[0003] Biopsy is the abbreviation of "living tissue examination", also known as surgical pathology examination, which refers to the technology of removing diseased tissue from the patient's body by cutting, clamping or puncturing for pathological examination in response to the needs of diagnosis and treatment. After searching, an endoscope biopsy cap disclosed in the application number CN201621210172.2 was found, which records that the utility model discloses an endoscope biopsy cap, including a biopsy cap body, one end of the biopsy cap body is provided with a biopsy cap cover, one side of the biopsy cap cover is fixedly connected to one side of the biopsy cap body through a hose, the biopsy cap cover is provided with a through hole communicating with the interior of the biopsy cap body, a safety plug is provided in the through hole, the material of the safety plug is transparent expansion plastic, and a pressure sensor for anti-reflux is provided at the end of the safety plug extending into the biopsy cap body, the pressure sensor is connected to a pressure display, the pressure display is arranged inside the safety plug and close to the other end of the safety plug. The utility model can ensure the sealing of the endoscopic examination space while ensuring a good field of view; can prevent digestive fluid from splashing and improve the self-protection ability of medical personnel; can detect the air pressure in the biopsy cap body in real time to provide a reference for the operation of the endoscope system, but the device still has the following defects in actual use: endoscopic biopsy refers to a diagnosis and treatment method for endoscopic doctors. During endoscopic examination, disposable endoscopic biopsy forceps are used to take the mucosa or diseased tissue in the patient's gastrointestinal tract out of the body through the endoscopic biopsy channel to determine whether the tumor is benign or malignant. This requires removing a part of the sample through the endoscopic examination for live detection, but the endoscopic tissue extraction component is inseparable from the endoscopic biopsy cap. Traditional endoscopic biopsy caps are mostly single. When taking out the sample, the cap will be damaged or the part where the sample is extracted will be enlarged over time. Although the sample is successfully taken out, the service life of the endoscopic biopsy cap is inevitably increased for this type of equipment. In addition, once damaged, it means that the entire biopsy cap is scrapped, which also indirectly causes a waste of materials. Summary of the invention

[0004] The utility model aims to provide a double-cover endoscopic biopsy cap to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above object, the present utility model provides the following technical solutions: a double-cover endoscopic biopsy cap, comprising an endoscopic biopsy mechanism and a bottom cover fastening mechanism;

[0029] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0030] Please refer to Figure 1 - Figure 8 , a double - cover endoscopic biopsy cap, comprising an endoscopic biopsy mechanism 1 and a bottom cover fastening mechanism 2;

[0031] The endoscopic biopsy mechanism 1 includes a conical sleeve 11 for taking out endoscopic samples. The barrel of the conical sleeve 11 is conical, hollow inside, and both the upper and lower ends of the conical sleeve 11 are penetrated and opened. It is installed at the biopsy channel opening of the endoscopic operation part. The bottom of the conical sleeve 11 is provided with a bottom cover fastening mechanism 2, and the top of the conical sleeve 11 is provided with a cover connection mechanism 4.

[0032] In this embodiment: A specimen collection cavity 12 is opened inside the conical sleeve 11, and both the upper and lower ends of the conical sleeve 11 are through - holes;

[0033] The bottom cover fastening mechanism 2 includes a lower bottom binding cover 21 arranged at the bottom of the conical sleeve 11. A lower bottom slot 22 is opened in the middle of the lower bottom binding cover 21, and the top of the slot position of the lower bottom slot 22 is in fit - socket connection with the bottom of the conical sleeve 11.

[0034] The adopted specimen collection cavity 12, conical sleeve 11 and the slot position of the lower bottom slot 22 are used as the access for the endoscopic diameter.

[0035] In this embodiment: An assembly pad 23 is provided in the middle of the top end of the conical sleeve 11, and a specimen retention opening is opened in the middle of the top end of the lower bottom binding cover 21. The hole position of the specimen retention opening is communicated with the specimen collection tube of the endoscope.

[0036] The sample is drawn into the interior of the tapered sleeve 11 by using the assembly pad 23 and the sample retention opening.

[0037] In this embodiment, a drain valve 24 is disposed on the back of the lower bottom binding cover 21 , and a liquid receiving bag 25 is externally connected to the surface of the drain valve 24 . The liquid receiving bag 25 is wrapped around the middle of the lower bottom binding cover 21 .

[0038] The liquid accumulation in the cap is collected by using the drain valve 24. The liquid can be transferred and diverted to the inside of the liquid receiving bag 25 after the drain valve 24 is opened. As the liquid is converted and extracted, more space is left to collect more samples, and the liquid accumulation in the biopsy cap can be conveniently sucked, thereby improving the suction efficiency.

[0039] Prevent a large amount of mucus or body fluids of the patient in the endoscopic biopsy channel from flowing back or splashing onto the consulting room or medical staff, avoid or reduce the risk of cross infection in the hospital. At the same time, the bottom of the biopsy cap is connected to the effusion bag. During diagnosis and treatment, the function of the discharge valve 24 is reduced due to the repeated use of treatment accessories in and out. The patient's body fluids flowing out of the endoscopic biopsy channel are collected in the effusion bag, reducing the contamination of the consulting room and medical staff.

[0040] The end of the tube of the catheter 34 used can be externally connected to a syringe, a treatment accessory or a water-filling device, and endoscopic treatment can be performed clinically.

[0041] In this embodiment: the outer wall of the lower bottom binding cover 21 is provided with a cover body connection mechanism 4, the cover body connection mechanism 4 includes a first side wall slot 41 arranged on the side wall of the lower bottom binding cover 21, a first clamping plug 42 is installed in the middle of the slot of the first side wall slot 41, one end of the first clamping plug 42 is clamped with an external buckle 43, the first clamping plug 42 is clamped and connected with the lower bottom binding cover 21, one end of the first clamping plug 42 is connected with a connecting pad 45 at the front end, an upper plug cover is provided at the end position of the buckle 43, a concave opening 46 is opened on the middle surface of the upper plug cover, and a sampling port blocking pad 47 is horizontally installed in the middle of the hole of the concave opening 46.

[0042] One end of the upper plug cover and the sampling port blocking pad 47 are connected to the top of the sampling cavity 12, and the first clamping plug 42 and the upper plug cover are sealed with the conical sleeve 11. If inspection is needed later, they can be replaced in time to the supplementary plugging mechanism 3. When the pressure in the patient's gastrointestinal tract is high, the biopsy cap will leak due to the repeated entry and exit of the treatment accessories during diagnosis and treatment, causing the entrance to become larger. During endoscopic diagnosis and treatment, the gastrointestinal tract needs to be continuously inflated to maintain a good endoscopic field of view. If the biopsy cap leaks, it will cause poor or difficult filling of the gastrointestinal tract, affecting the patient's diagnosis and treatment. The use of a biopsy port blocking pad can avoid such incidents. Therefore, the supplementary plugging mechanism 3 is used to ensure that the biopsy cap can be smoothly used for biopsy during surgery in the later stage.

[0043] In this embodiment: A rear filling mechanism 3 is provided on the side of the lower bottom binding cover 21 on the other side, and a spare cap is provided on the surface of the rear filling mechanism 3;

[0044] The rear filling mechanism 3 includes a second side wall slot 31 provided on the other side of the lower bottom binding cover 21. One end of the second side wall slot 31 is connected with a spare gasket 33 through a second clamping plug 32, and a conduit 34 is provided at the padding end of the spare gasket 33.

[0045] The second clamping plug 32 and the spare gasket 33 are used to achieve access connection.

[0046] Step 1: Connect the double-cap endoscopic biopsy cap to the outlet part of the endoscope biopsy tube diameter;

[0047] First, the sampling cavity 12 is used as a means of connecting with the endoscope sample. Note that the narrow upper part of the conical sleeve 11 is sleeved with the cover body connection mechanism 4, and the interface part is blocked by a sealing means when no sample is taken to prevent dust from falling into the sampling cavity 12 and causing sample contamination;

[0048] In addition, the innovation of this biopsy cap lies in the means of providing two detachable first side wall slots 41 at the position of the lower bottom binding cover 21. After the buckle 43 and the first clamping plug 42 are fastened, the connection pad 45 is connected. The second one is the same principle. After the second clamping plug 32 is inserted into the second side wall slot 31, the disassembly or installation can be completed by using the buckle 43;

[0049] Step 2: Then connect the lower bottom binding cover 21 to the bottom of the conical sleeve 11

[0050] In this way, when taking the patient's biopsy cells, the biopsy sample can be brought along the endoscope tube diameter position from the lower bottom slot 22 opened at the bottom of the lower bottom binding cover 21 to the lower bottom slot 22, and then transferred based on the inner wall space of the conical sleeve 11. Some biopsy effusions will be reversely poured into this space during the biopsy collection, ensuring that there is enough space to store the sample;

[0051] It is necessary to consider that the entrained effusion will fill the sampling cavity 12 and be transferred into the liquid receiving bag 25. Drain the excess effusion and only retain a part, so that more tissues can be stored;

[0052] In addition, considering a single lid connection mechanism 4 alone, firstly, one lid structure is not sufficient, and secondly, the entire lid including the conical sleeve 11 has to be scrapped once it is damaged. Moreover, the damaged part is rather special. During clinical use, the conical sleeve 11 will not be damaged, but the connection pad 45 is prone to damage. In addition, two types of lids need to be set up during sample retrieval. One is directly sealed for use before the sample is collected. After the biopsy sample is transferred into the conical sleeve 11, another structure with a catheter 34 is replaced additionally, which is more convenient for later transfer.

[0053] In addition, it is considered that the biopsy sample transfer is further completed by expanding the sealing area of the connection pad 45 or the position of the catheter 34 area.

[0054] In addition, a sampling port plugging pad 47 is used to seal the position of the conical sleeve 11.

[0055] The disassembly connection is achieved by using the slot positions of the first clamping plug 42 and the first side wall slot 41.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
