Description

Technical Field

[0001] This utility model relates to the field of ultrasonic endoscopy technology, specifically to a probe sleeve for ultrasonic endoscopy. Background Technology

[0002] Endoscopic ultrasound (EUS) is an important medical examination device widely used for examining internal organs such as the digestive tract, biliary tract, and pancreas. EUS is divided into large-probe EUS and small-probe EUS. The probe of an EUS is usually very small and can be placed at the end of the endoscope or extended to the target organ through the biopsy forceps channel of the endoscope. The probe of an EUS is designed with a built-in water injection channel. During the EUS examination, in order to ensure that the ultrasound waves can be well transmitted to the patient's body, a sealed bag is usually placed on the probe, and liquid is injected into the bag through the water injection channel to create a water environment. This water environment can act as a transmission medium for ultrasound waves and improve the clarity of ultrasound images.

[0003] Currently, most commonly used sealing bags for ultrasound endoscopy use polyurethane material for support. Although they can adapt to changes in the shape of the probe and ensure a certain degree of sealing effect, their usage cost is relatively high, and they are prone to falling off, causing inconvenience to medical staff. Therefore, a probe cover for ultrasound endoscopy is proposed to address the above issues. Utility Model Content

[0004] The purpose of this invention is to provide a probe sleeve for ultrasound endoscopy, which uses cut nano double-sided adhesive tape as a sleeve to wrap around the tip of the endoscope, resulting in lower cost and better sealing. This solves the problems of relatively high cost and easy detachment of traditional sealing bags.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a probe sleeve for ultrasound endoscopy, including a sleeve, a support, an endoscope tip, a first fixing member and a second fixing member. There are at least two support members, and both support members are bonded to the endoscope tip to form a ring. The endoscope tip cooperates with the two support members to form a recessed area.

[0007] When the center of the connector is bonded to the tip of the endoscope and a sealed capsule is formed by wrapping around the tip of the endoscope, the connector is bonded to the two support members. The connector is recessed downward at the position of the recessed area and forms a recessed positioning part after contacting the surface of the tip of the endoscope.

[0008] One end of the first fixing member is bonded to the recessed positioning part, and after wrapping around the recessed positioning part once, the ends are bonded together. One end of the second fixing member is bonded to the tail of the cyst, and after wrapping around the sleeve once, the ends are bonded together.

[0009] Furthermore, the socket has a rectangular structure and is made by cutting nano double-sided adhesive tape.

[0010] Furthermore, the support, the first fixing member, and the second fixing member are all elongated strips in shape, and all three are made of nano double-sided adhesive tape.

[0011] Furthermore, the recessed positioning part is annular, and the distance between the two ends of the recessed positioning part is the same as the distance between the two ends of the first fixing member after it has been wrapped around once.

[0012] Furthermore, when the second fixation member is bonded to the tail of the cyst, the second fixation member is also bonded to the outer surface of the tip of the endoscope.

[0013] This utility model has the following beneficial effects:

[0014] This invention uses cut nano double-sided tape as a sleeve to wrap around the tip of an endoscope. The self-adhesive properties of the nano double-sided tape form a water bladder structure to replace the traditional sealed bag. Compared with polyurethane materials, it is less expensive and helps to reduce the examination costs for patients.

[0015] This invention further seals the end of the socket by using a second fastener to further bond and fix it after wrapping, thereby improving the sealing performance of the water bladder formed after the socket and the endoscope tip are assembled, and also improving the anti-detachment ability of the socket after assembly.

[0016] This utility model, through its structural design of a support member, a recessed area, a recessed positioning part, and a first fixing member, can further improve the positioning and sealing effect after the fitting parts are assembled and the first fixing member is bonded to the recessed positioning part. This effectively enhances the stability of the water bladder structure, avoids the risk of the water bladder falling off during inspection, and improves the safety and reliability of the inspection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a probe sleeve for ultrasound endoscopy, including a sleeve 1, a support 2, an endoscope tip 3, a first fixing member 4, and a second fixing member 5.

[0024] The socket 1 has a rectangular structure and is made by cutting nano double-sided tape.

[0025] The support member 2, the first fixing member 4, and the second fixing member 5 are all elongated strips, and all three are made of nano double-sided adhesive tape.

[0026] Using nano double-sided tape cut into a socket 1, support 2, first fixing 4 and second fixing 5, a capsule-like body is formed by the socket 1, and a sealed capsule-like body is formed by the first fixing 4 and the second fixing 5. The overall cost is lower and the sealing performance is better.

[0027] The support member 2 has at least two members, and both support members 2 are bonded to the endoscope tip 3 to form a ring. The endoscope tip 3 and the two support members 2 cooperate to form a recessed area 201.

[0028] When the center of the sleeve 1 is bonded to the tip 3 of the endoscope, and a sealed capsule is formed by wrapping around the tip 3 of the endoscope, the sleeve 1 is bonded to the two support members 2. When the sleeve 1 is pressed down by external force at the position of the recessed area 201, it forms a recessed positioning part 101 after contacting the surface of the tip 3 of the endoscope.

[0029] One end of the first fixing member 4 is bonded to the recessed positioning part 101, and after wrapping around the recessed positioning part 101 once, the ends are bonded together.

[0030] The recessed positioning part 101 is circular after being pressed, and the distance between the two ends of the recessed positioning part 101 is the same as the distance between the two ends of the first fixing member 4 after it is wrapped around once.

[0031] Correspondingly, by setting the first fixing member 4 in the recessed positioning part 101, the positioning and sealing effect can be further improved, the stability of the water bag structure can be effectively enhanced, the risk of the water bag falling off during the inspection process can be avoided, and the safety and reliability of the inspection can be improved.

[0032] One end of the second fixing member 5 is bonded to the tail of the cyst, and after wrapping around the sleeve member 1 once, the ends are bonded together.

[0033] When the second fixing member 5 is bonded to the tail of the cyst, the second fixing member 5 is also bonded to the outer surface of the endoscope tip 3.

[0034] In this embodiment, during use, firstly, two long strips of nano double-sided adhesive tape are adhered around the endoscope tip 3 to form two support members 2, thereby creating a recessed area 201 between the two support members 2. Then, rectangular nano double-sided adhesive tape is taken out and wrapped around the endoscope tip 3. Figure 2 After bonding as shown, it becomes Figure 3 The shape shown ensures that the sleeve 1 and the endoscope tip 3 are completely bonded to form a sealed capsule. After pressing the capsule, the capsule is recessed downwards at the recessed area 201 and bonded to the endoscope tip 3, forming a recessed positioning part 101. Then, a long strip of nano double-sided tape is wrapped around the tail of the capsule and bonded to the tail of the capsule. At the same time, the long strip of nano double-sided tape is bonded to the endoscope tip 3 to form a second fixing member 5. Then, a long strip of nano double-sided tape is wrapped around the recessed positioning part 101 and bonded to the sleeve 1.

[0035] After the cyst body is installed and further sealed, a small probe is inserted through the channel on the endoscope tip 3, and water is injected into the cyst body through the water injection channel on the probe, so that the cyst body forms a water sac. By observing whether there is any leakage, if there is no leakage, the water is extracted, and the endoscope tip 3 encasing the cyst body is inserted into the cavity to reach the ultrasound site. The small probe is inserted through the biopsy channel of the endoscope, and the water sac is used as a medium for ultrasound detection.
