Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a subdural hematoma contact imaging drainage device. Background Technology

[0002] With the continuous advancement of medical technology and the increasing demands of patients for treatment outcomes, the application prospects of subdural hematoma contact imaging drainage devices are becoming increasingly broad in clinical practice. This device can not only improve the precision and safety of surgery, but also reduce patient suffering and the occurrence of complications. In the future, with further development and improvement of the technology, this device is expected to be applied in more types of neurosurgical procedures.

[0003] Drainage devices are used to drain blood or fluid from the hematoma cavity. The drainage tubes on the drainage devices may be designed with special shapes or structures, such as multi-branch designs, to set drainage channels in multiple directions, ensuring that fluid in all directions can be effectively drained. Subdural hematoma refers to intracranial hemorrhage where blood accumulates in the subdural space. It has the highest incidence among intracranial hematomas and is a very common disease in neurosurgery. Drilling and placing drainage tubes are necessary to relieve the pressure of the hematoma on the brain tissue and to treat the patient.

[0004] The current drainage device has the following drawbacks. It first determines the location of the hematoma by using a contact imaging instrument, and then removes the hematoma by using a drainage device. The drawback is that the positioning and drainage are performed separately. When inserting the drainage tube, the placement may be inaccurate, which is not conducive to the elimination of the hematoma. Therefore, a subdural hematoma contact imaging drainage device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a subdural hematoma contact imaging drainage device, which aims to improve upon the existing technology, which currently determines the location of the hematoma first through a contact imaging instrument and then removes the hematoma through a drainage device. The drawback of this technology is that the positioning and drainage are performed separately, and there may be deviations in the placement of the drainage tube.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a subdural hematoma contact imaging drainage device, comprising a drainage device body, a control panel, and a transparent catheter. The transparent catheter is equipped with an adjustment mechanism, which in turn is equipped with an auxiliary mechanism. The adjustment mechanism includes a drainage tube, which is snapped into the inner side wall of the transparent catheter. An opening is formed in the outer side wall of the drainage tube. An installation cylinder is snapped into the inner wall of the right end of the drainage tube. A contact imaging instrument wire is fixedly connected to the left end of the installation cylinder. A camera is fixedly connected to the left end of the contact imaging instrument wire. A viewing window is formed in the outer top wall of the transparent catheter.

[0007] As a further description of the above technical solution: the auxiliary mechanism includes an internal thread, which is formed on the inner side wall of the drainage tube. The inner side wall of the internal thread is threaded with a first external thread, and the outer side wall of the transparent conduit is provided with a second external thread. The inner left side wall of the main body of the drainage device is provided with an installation hole.

[0008] As a further description of the above technical solution: the camera is clipped onto the inner wall of one side of the transparent conduit, and a gap is left between the drainage tube and the transparent conduit.

[0009] As a further description of the above technical solution: a transmission line is fixedly connected to the right end of the mounting cylinder, and the end of the transmission line away from the mounting cylinder is fixedly connected to the inner wall of one side of the main body of the drainage device.

[0010] As a further description of the above technical solution: there are several openings, and the several openings are circumferentially formed on the outer side wall of the drainage tube, and the openings are connected to the transparent catheter.

[0011] As a further description of the above technical solution: the first external thread is threadedly connected to the internal thread, and the second external thread is threadedly connected to the inner wall of the mounting hole inner ring.

[0012] As a further description of the above technical solution: a directional mark is provided on the right outer wall of the mounting cylinder.

[0013] As a further description of the above technical solution: the control panel is fixedly connected to the front outer wall of the main body of the drainage device, and the transparent catheter is snapped into the left inner wall of the main body of the drainage device.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the transparent catheter, the drainage tube, and the contact imaging device wire are of the same length, and the contact imaging device and the drainage tube can be detachably fixed inside the transparent catheter. When the transparent catheter reaches the hematoma location, the contact imaging device wire can be removed, and then the drainage tube can be passed through the inside of the transparent catheter directly to the hematoma.

[0016] 2. In this utility model, the transparent catheter is provided with an opening, and the contact imaging instrument wire and drainage tube inserted into the transparent catheter do not contact the transparent catheter. During the operation, some body fluid can flow into the gap between the transparent catheter and the contact imaging instrument wire or drainage tube through the opening, which can reduce the pressure of the transparent catheter on the brain tissue.

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.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a subdural hematoma contact imaging drainage device, comprising a drainage device body 1, a control panel 2, and a transparent catheter 3. A dispensing mechanism 4 is provided on the transparent catheter 3, and an auxiliary mechanism 5 is provided on the dispensing mechanism 4. The dispensing mechanism 4 includes a drainage tube 41, which is snapped into the inner side wall of the transparent catheter 3. An opening 42 is provided on the outer side wall of the drainage tube 41. An installation cylinder 43 is snapped into the inner wall of the right end of the drainage tube 41. The transparent catheter 3 is of a length compatible with the drainage tube 41. A contact imaging instrument line 44 is fixedly connected to the left end of the installation cylinder 43, and a camera 45 is fixedly connected to the left end of the contact imaging instrument line 44. A viewing window 46 is provided on the outer top wall of the transparent catheter 3, allowing the camera 45 to observe the external environment from a planar perspective.

[0025] Reference Figures 2-4The camera 45 is clipped onto the inner wall of one side of the transparent conduit 3. A gap is left between the drainage tube 41 and the transparent conduit 3. A transmission line 47 is fixedly connected to the right end of the mounting cylinder 43. The end of the transmission line 47 away from the mounting cylinder 43 is fixedly connected to the inner wall of one side of the drainage device body 1. The angle information monitored by the camera 45 is transmitted to the drainage device body 1 by setting the transmission line 47. There are several openings 42. Several openings 42 are opened in a ring on the outer side of the drainage tube 41. The openings 42 are connected to the transparent conduit 3. The control panel 2 is fixedly connected to the outer front wall of the drainage device body 1. The transparent conduit 3 is clipped onto the inner left side wall of the drainage device body 1.

[0026] Reference Figures 3-4 The auxiliary mechanism 5 includes an internal thread 51, which is formed on the inner side wall of the drainage tube 41. The inner side wall of the internal thread 51 is threaded with a first external thread 52. The outer side wall of the transparent conduit 3 is provided with a second external thread 53. By setting the second external thread 53 to cooperate with the mounting hole 54, the drainage tube 41 and the drainage device body 1 can be easily separated and assembled. The inner left wall of the drainage device body 1 is provided with a mounting hole 54. The first external thread 52 is threaded with the internal thread 51. The second external thread 53 is threaded with the inner wall of the inner ring of the mounting hole 54. The outer right wall of the mounting cylinder 43 is provided with a directional mark to indicate the rotation direction for disassembly and assembly.

[0027] Working principle: During the surgery, the imaging instrument wire 44 is first connected to the transparent catheter 3 via threads. Then, the transparent catheter 3 is slowly inserted into the body, and the camera 45 in the imaging instrument wire 44 probes the hematoma through the transparent catheter 3. After the location of the hematoma is determined, the transparent catheter 3 is kept still, and the imaging instrument wire 44 and camera 45 are removed from the transparent catheter 3. Then, the drainage tube 41 is introduced into the transparent catheter 3 and fixed with its threads. The hematoma can then be drained through the main body 1 of the drainage device. Throughout the entire surgical process, because the transparent catheter 3 has an opening 42, and the imaging instrument wire 44 or the drainage tube 41 do not contact the transparent catheter 3 except at the threaded connection, leaving a gap, some body fluid can flow into the gap between the transparent catheter 3 and the imaging instrument wire 44 or the drainage tube 41 through the opening 42, which can reduce the pressure of the transparent catheter 3 on the brain tissue.
