Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a drainage tube dedicated to pancreatic surgery. Background Art

[0002] A drainage tube is usually a tube placed in a cavity in the patient's body after surgery that connects to the outside world. It allows some tissue fluid or pus that seeps from the surgical site to flow out of the body, so that too much tissue fluid or pus will not remain in the body, because these things can easily lead to infection in the body for a long time. After the fluid in the drainage tube gradually decreases, the drainage tube can be removed, so that the possibility of infection in the body is much smaller, which helps the healing of internal wounds.

[0003] However, when the current drainage tube is used, when it is necessary to retract the drainage tube, the sutures fixing the drainage tube on the skin need to be untied, which causes certain damage to the human body surface and is not very convenient for removing the drainage tube; in addition, the general drainage tube usually blocks the drainage hole during use, thereby affecting the drainage amount during the use of the drainage tube.

[0023] The utility model is further described in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1 to 4 As shown, the drainage tube dedicated to pancreatic surgery described in the utility model is characterized by comprising a fixator 1, a drainage tube 2, a limiting groove 3, a clamping groove 4, a fixing head 5, and a clamping assembly 6;

[0025] The fixer 1 is fixed on the surface of human skin through a patch; the drainage tube 2 passes through the fixer 1; the middle part of the fixer 1 is a hollow structure, and the limiting groove 3 is provided on the middle inner wall of the fixer 1; the top of the fixer 1 is provided with four evenly distributed card slots 4; the four card slots 4 are connected to the limiting groove 3; the drainage tube 2 is provided with the fixing head 5 at the part passing through the fixer 1; the fixing head 5 is clamped into the inside of the fixer 1, and the fixing head 5 is fixedly connected to the drainage tube 2; the fixing head 5 is provided with the clamping assembly 6.

[0026] The drainage tube 2 body is cross-groove-shaped; the groove portion between the cross end faces of the drainage tube 2 is provided with drainage holes 7. By setting the drainage tube 2 in a cross-shaped structure, the clogging of the drainage tube 2 is further avoided.

[0027] The clamping assembly 6 includes a cross groove 61, a hexagonal angle marking head 62, a spring 63, and a clamping block 64;

[0028] The middle of the fixing head 5 is provided with the cross groove 61 for the cross-shaped drainage tube 2 to pass through; the top of the fixing head 5 is fixedly connected with a hexagonal angle marking head 62; four springs 63 are evenly distributed on the side wall of the fixing head 5; the other end of the spring 63 is fixedly connected with the clamping block 64; when the fixing head 5 and the fixer 1 are clamped and fixed, the clamping block 64 is clamped from the clamping groove 4 into the inside of the limiting groove 3. By setting a new clamping structure between the drainage tube 2 and the fixer 1, the problem of the need to untie the suture thread fixing the drainage tube 2 on the skin when the drainage tube 2 on the market needs to be retracted is avoided.

[0029] The outer wall of the fixture 1 is a hexagonal structure, and the surface of the fixture 1 is provided with a graduation mark for conveniently observing the rotation angle of the fixing head 5. By setting the fixture 1 with a hexagonal structure and providing an angle mark on the fixture 1, it is convenient to observe the drainage situation inside the drainage tube 2.

[0030] Working principle: Fix the fixer 1 through the patch. When the fixing head 5 and the fixer 1 are fixed by clamping, the clamping block 64 is clamped into the inside of the limiting groove 3 from the clamping slot 4. After the drainage tube 2 is rotated, the drainage tube 2 can be fixed by limiting. The growth of granulation tissue inside the drainage tube 2 can be observed by observing the rotation angle of the fixing head 5. When the drainage volume decreases, the drainage tube 2 is rotated so that the clamping block 64 is located on the clamping slot 4, and then the drainage tube 2 is pulled out for observation and cleaning. This avoids the need to untie the sutures that fix the drainage tube 2 on the skin when the drainage tube 2 on the market needs to be withdrawn. When the angle of each rotation of the fixing head 5 is sixty degrees, that is, when the fixing head 5 and the fixer 1 overlap, an observation can be performed for easy recording. The contents not described in detail in this specification belong to the prior art known to professionals in this field.

[0031] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but the utility model is not limited to these embodiments. It should be pointed out that for ordinary technicians in this field. Under the premise of not departing from the purpose of the utility model, any improvement made shall fall within the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
