AI Technical Summary
Postoperative bleeding is a common complication of transurethral prostatectomy. The current catheter retraction method is limited and increases the patient's discomfort, stimulates bladder spasm, and makes it difficult to effectively control bleeding.
A prostate compression hematuria catheter was designed, with a flexible water sac fixed at the front of the urethra, which was pear-shaped after filling water, which was in line with the anatomical shape of the bladder-prostate fossa. The snap structure on the urethra catheter was used in conjunction with the fixing device to achieve compression hematuria.
The pear-shaped structure of the flexible water sac effectively compresses the prostate wound and improves the hemostasis effect; the snap structure is convenient to fix, reducing patient discomfort and reducing the occurrence of bladder spasm.

Abstract
Description
Technical Field
[0001] The utility model relates to a medical device, in particular to a prostate compression hemostasis ureter Background Art
[0002] Transurethral prostatectomy (including a type of surgery with different surgical procedures and energy platforms) is the main surgical treatment for benign prostatic hyperplasia. Postoperative bleeding is one of the more common complications. Possible causes include: excessively deep tissue resection during surgery, incomplete hemostasis, and scab shedding caused by postoperative bladder spasm. Bladder spasm is mostly caused by stimulation from the postoperative indwelling urinary catheter. Although for some patients, timely traction, compression and symptomatic treatment can reduce bleeding, some patients still cannot effectively control bleeding after the above conservative treatment and need to undergo another surgery, which has a certain impact on the patient's physical and mental health and increases the economic burden.
[0003] Currently, the method of pulling the urinary catheter is usually to tie a gauze around the glans penis. On the one hand, the pulling effect is limited, and on the other hand, it will increase the patient's discomfort and stimulate bladder spasm. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a prostate compression hemostasis catheter, which can reduce the discomfort of the patient as much as possible and reduce bladder spasm while achieving compression hemostasis by pulling the catheter.
[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0006] The utility model discloses a prostate compression hemostasis urinary catheter, comprising a urinary catheter, which is characterized in that a flexible water bag is fixedly arranged at the front of the urinary catheter, and the inner cavity of the flexible water bag is pear-shaped with a larger front and a smaller back after being filled with water; the cross section of the urinary catheter is provided with a urination channel which runs longitudinally, and a water injection and drainage channel whose front end is connected with the inner cavity of the flexible water bag.
[0007] A radially outwardly protruding buckle structure is arranged at intervals on the urinary catheter body behind the flexible water bag.
[0008] The beneficial effect of the utility model is that after the inner cavity of the flexible water bag is filled with water, it becomes a pear shape with a larger front and a smaller back, which conforms to the anatomical shape of the bladder-prostate fossa and can effectively compress the patient's prostate wound surface, and has a better hemostatic effect; through the buckle structure on the catheter, it can be conveniently used in conjunction with the fixing device, and can better achieve pulling the catheter to compress and stop bleeding. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] This specification includes the following three drawings:
[0010] Figure 1 It is a structural schematic diagram of a prostate compression hemostasis ureter of the utility model;
[0011] Figure 2 It is a partially enlarged schematic diagram of a prostate compression hemostasis ureter of the utility model;
[0012] Figure 3 This is a schematic diagram of the cross-sectional structure of a prostate compression hemostasis ureter of the utility model;
[0013] The figure shows the components and corresponding marks: a urine catheter 10 , a urination channel 11 , a water injection and drainage channel 12 , a snap structure 13 , and a flexible water bag 20 . DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0015] Reference Figure 1 to Figure 2 The utility model is a prostate compression hemostasis catheter, comprising a catheter 10, wherein a flexible water bag 20 is fixedly arranged at the front of the catheter 10. After the inner cavity of the flexible water bag 20 is filled with water, it becomes a pear shape with a larger front and a smaller back, which conforms to the anatomical shape of the bladder-prostate fossa and has a better compression hemostasis effect. Figure 3 The cross section of the urinary catheter 10 is provided with a longitudinally penetrating urination passage 11 and a water injection and drainage passage 12 whose front end is connected to the inner cavity of the flexible water bag 20 .
[0016] Reference Figure 1 When in use, after the front part of the urethra 10 is placed into the urethra and bladder, sterile saline is injected through the water injection and drainage channel 12 to expand the flexible water bag 20 into a pear shape with a larger front and a smaller back. The distal end is located in the bladder and is used for the urethra 10, and the proximal end is located in the prostate fossa, which can effectively compress the prostate wound surface and has a better hemostatic effect.
[0017] Reference Figure 1 In order to facilitate the use with the fixing device and better achieve the pulling of the urinary catheter to compress and stop bleeding, the urinary catheter 10 behind the flexible water bag 20 is provided with radially outwardly protruding buckle structures 13 at intervals, and a hydrogel patch is provided on the side of the buckle structure 13 closest to the flexible water bag 20. That is, the buckle structures 13 with different scales on the outer wall of the urinary catheter 10 are suitable for patients with different penis lengths, and are used to cooperate with the fixing device of the urinary catheter 10 to strengthen the fixation and pulling, and play a role in assisting the flexible water bag 20 to compress the wound surface and stop bleeding.
[0018] The above description is only to illustrate some principles of the prostate compression hemostatic catheter of the utility model, and is not intended to limit the utility model to the specific structure and applicable scope shown and described. Therefore, all corresponding modifications and equivalents that may be used are within the scope of the patent applied for by the utility model.
