Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a specimen collection device for transurethral resection surgery. Background Technology
[0002] Transurethral resection of the urethra (TURP) is a common surgical procedure in urology, widely used in the treatment of benign prostatic hyperplasia and bladder tumors. Its main principle is to locate the lesion under direct vision, then use a plasma resection ring to remove the lesion in sections. Hemostasis is then achieved at the base of the excised wound using the resection ring. The excised specimen fragments are flushed out with irrigation fluid through the resection endoscope sheath and collected. Currently, specimen collection is mainly done using a collection device made of gauze and a plastic basin. For specimens from multiple resection sites, it is necessary to collect specimens from different sites separately. However, existing specimen collection devices can only collect a single specimen. After collecting a specimen from one site, a new collection device needs to be installed to collect specimens from another site, which is extremely inconvenient and makes it easy to mix up surgical specimens from different sites during the procedure. Utility Model Content

[0029] Example 1
[0030] In one specific embodiment of this utility model, a specimen collection device for transurethral resection of tissue is disclosed. This device is used to collect specimens from multiple lesions removed during transurethral resection of tissue separately, preventing confusion of surgical specimens from different sites during the procedure. Figure 1As shown, the device includes a waste fluid collection container 1, a loader 2, a specimen collector 3, and a cap 4. The loader 2 is rotatably installed inside the waste fluid collection container 1. Multiple specimen collectors 3 are arranged circumferentially on the loader 2. The cap 4 is fastened to the opening of the waste fluid collection container 1 and connected to the electrosurgical resection scope sheath. In use, multiple specimen collectors 3 are installed on the loader 2, then the loader 2 is installed inside the waste fluid collection container 1. The cap 4 is then fastened to the opening of the waste fluid collection container 1 and connected to the electrosurgical resection scope sheath. The electrosurgical resection ring removes the lesion tissue. The removed lesion tissue (i.e., the specimen) is then passed through the electrosurgical resection scope sheath along with the waste fluid. The specimen is fed into specimen collector 3, filtered and collected, while waste liquid is temporarily stored in waste liquid collection container 1. When it is necessary to remove lesions from different sites, the loader 2 is rotated to switch to an empty specimen collector 3 for targeted collection. Compared with existing specimen collection devices, this embodiment achieves separate collection of specimens from different sites without changing to a new specimen collection device when performing multi-point lesion tissue removal by rotating the loader 2 to switch between different specimen collectors 3. This avoids confusion of surgical specimens from different sites, is convenient to operate, reduces the workload of medical personnel, speeds up the surgical process, and at the same time alleviates the patient's pain.

[0036] Preferably, such as Figure 6 As shown, the collection box 31 is also provided with a fixing slot 312, which is located at the open end of the collection box 31 and is used to insert the cover plate 32 and fix the cover plate 32.
[0037] Preferably, the waste liquid collection container 1 is also provided with a guide slot 12, which can be opposite to the fixed slot 312. After the collection box 31 collects the specimen, the cover plate 32 can be smoothly inserted into the fixed slot 312 through the guide slot 12 to seal the collection box 31.
[0038] Preferably, the guide slot 12 is on the same side as the liquid inlet 41, that is, the guide slot 12 is opposite to the liquid inlet 41. When the collection box 31 is empty, the cover plate 32 is not inserted into the fixing slot 312. After the collection box 31 collects the specimen, the cover plate 32 is inserted into the fixing slot 312. Whether the cover plate 32 can be inserted into the fixing slot 312 through the guide slot 12 can quickly determine whether the collection box 31 opposite to the liquid inlet 41 is empty, so as to avoid the mixing of specimens from different positions.
[0039] Preferably, the collection box 31 is further provided with a marking block 313, which is set at the opening end of the collection box 31 and is used to mark the part of the specimen contained in the collection box 31, so as to further prevent the confusion of specimens from different parts.
