Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a neurosurgical guide that is easy to use in clinical practice. Background Technology

[0002] Hypertensive intracerebral hemorrhage (HICH) is a disease caused by long-term hypertension leading to pathological changes in intracranial arterioles, including hyaline or fibrous degeneration of the vessel walls, which weakens the elasticity of the vessel walls and causes rupture and bleeding. When a patient experiences emotional excitement, excessive mental or physical activity, or other factors that cause a sharp rise in blood pressure, cerebral hemorrhage can occur. Common sites of hemorrhage in HICH include the basal ganglia, ventricles, thalamus, cerebellum, brainstem, lobes, and subcortex. In the lobes and subcortex, rupture of small aneurysms caused by angioamyloidosis is common. Due to the extremely high mortality and disability rates of HICH, improving the clinical surgical treatment capabilities and levels has become a crucial task. Clinical surgical treatments for HICH include large craniotomy or small craniotomy for hematoma evacuation, burr hole drainage of the hematoma, stereotactic hematoma aspiration, and neuroendoscopic hematoma evacuation.

[0003] With the development of neurosurgery from gross neurosurgery to microsurgical neurosurgery and minimally invasive neurosurgery, neuroendoscopy has become one of the main instruments in minimally invasive neurosurgery.

[0004] Neurosurgical procedures, especially those related to cerebral hemorrhage or cerebral hematoma, require doctors to use guides to perform various procedures such as aspiration of blood, irrigation, electrocoagulation, and endoscopy to assist in the surgery.

[0005] The functions of the guide, such as blood aspiration, irrigation, electrocoagulation, and endoscopy, are mainly achieved through multiple tubes extending from the guide into the patient's body. In the existing technology, the ends of the multiple tubes of the guide (the end that enters the guide) are integrated into one place of the guide. Since the aspiration tube and irrigation tube require external equipment tubing, and bipolar electrocoagulation also requires the insertion of an instrument channel to enter the lesion area during intraoperative hemostasis, the external tubing and instruments are prone to mutual interference during surgery, which is very inconvenient.

[0006] In view of this, there is an urgent need for a neurosurgical guide that is easy to use in clinical practice to solve the above problems. Utility Model Content

[0007] To help solve the problems existing in the prior art, this utility model provides a neurosurgical guide that is easy to use in clinical practice. The technical solution is as follows: a guide body and a tubing mechanism. The guide body includes a handle, a guide part and a guide tube. The guide part is disposed at the top of the handle and the guide tube is disposed at one end of the guide part.

[0008] The tubing system includes a suction tube, a flushing tube, and an instrument tube. The suction tube and the flushing tube extend from the end of the handle away from the guide to the end of the guide tube, and the instrument tube extends from the end of the guide away from the guide to the end of the guide tube.

[0009] Its further feature is that,

[0010] The tubing mechanism also includes an endoscope cable. A threading hole is provided on one side of the handle. The endoscope cable passes through the threading hole into the handle and extends to the end of the guide tube.

[0011] The guide tube is provided with several guide channels, which pass through the guide tube. The several guide channels are set independently, and the suction tube, flushing tube, instrument tube and endoscope wiring are respectively passed through one of the guide channels.

[0012] The suction tube and endoscope circuit at the guide tube are located on opposite sides.

[0013] The flushing tube and instrument tube at the guide tube are located on opposite sides.

[0014] Both the suction tube and the flushing tube have connectors at the ends furthest from the guide tube.

[0015] A retaining plate is provided inside the handle, and two slots are provided on the retaining plate. One end of each of the two connectors is respectively located in one of the two slots.

[0016] The handle is provided with two limiting components, each including two limiting plates arranged side by side, with a limiting channel between the two limiting plates. The suction tube and the rinsing tube pass through the two limiting channels respectively.

[0017] The handle is provided with a first control component for controlling the flow rate of the suction tube or flushing tube.

[0018] The guide section is provided with a second control component for controlling the extension length of the suction tube or rinsing tube beyond the end of the guide tube.

[0019] The above-described structure of this utility model can achieve the following beneficial effects:

[0020] By inserting the suction tube and irrigation tube into the tail of the handle, and the instrument tube into the end of the guide tube away from the guide tube, when holding the guide body, the external device tubing connecting the suction tube and irrigation tube is located at the bottom of the palm, while the instrument tube is located at the top of the palm, and the two do not interfere with each other, making it more convenient for doctors to use.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0029] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0030] Reference Figure 1-2 A neurosurgical guide for clinical use includes: a guide body 100 and a tubing mechanism. The guide body includes a handle 110, a guide portion 120 and a guide tube 130. The guide portion 120 is disposed at the top end of the handle 110 and the guide tube 130 is disposed at one end of the guide portion 120.

[0031] The tubing system includes a suction tube 200, a flushing tube 300, and an instrument tube 400. The suction tube 200 and the flushing tube 300 extend from the end of the handle 110 away from the guide portion 120 to the end of the guide tube 130. The instrument tube 400 extends from the end of the guide portion 120 away from the guide tube 130 to the end of the guide tube 130.

[0032] Based on the above structure, by inserting the suction tube 200 and the irrigation tube 300 through the tail of the handle 110, and the instrument tube 400 through the end of the guide 120 away from the guide tube 130, when holding the guide body 100, the external device tubing connecting the suction tube 200 and the irrigation tube 300 is located at the bottom of the palm (little finger side), while the instrument tube 400 is located at the top of the palm (thumb side), and the two do not interfere with each other, making it more convenient for doctors to use.

[0033] like Figure 2 As shown, the tubing mechanism also includes an endoscope cable. A wire hole 111 is provided on one side of the handle 110. The endoscope cable passes through the wire hole 111 into the handle 110 and extends to the end of the guide tube 130. This avoids the endoscope cable from interfering with the use of the instrument in the instrument tube 400. Other internal cables can also pass through the wire hole 111.

[0034] like Figure 3 As shown, the guide tube 130 is provided with several guide channels 131, which pass through the guide tube 130. The guide channels 131 are independently arranged. The suction tube 200, the flushing tube 300, the instrument tube 400, and the endoscope wiring are respectively passed through one of the guide channels 131. In this way, the tubes do not interfere with each other and will not be tangled together. Furthermore, the suction tube 200 and the endoscope wiring are located on opposite sides of the guide tube 130, while the flushing tube 300 and the instrument tube 400 are located on opposite sides of the guide tube 130.

[0035] like Figure 2 As shown, in order to facilitate the connection with external equipment, the ends of the suction tube 200 and the flushing tube 300 away from the guide tube 130 are both provided with connectors 500; and a retaining plate 600 is provided inside the handle 110. The retaining plate 600 is provided with two slots. One end of the two connectors 500 is respectively located in the two slots, and the two ring plates on the connectors 500 are respectively locked on both sides of the retaining plate 600, so that the connectors 500 are firmly fixed at the handle 110 and prevent them from falling off.

[0036] like Figure 2As shown, to avoid interference between the pipes at the handle, two limiting components are provided inside the handle 110. The limiting components include two limiting plates 700 arranged in parallel, with a limiting channel between the two limiting plates 700. The suction tube 200 and the flushing tube 300 pass through the two limiting channels respectively. The two limiting components limit the suction tube 200 and the flushing tube 300 respectively, preventing the suction tube 200 and the flushing tube 300 from moving at the handle 110 and causing interference.

[0037] Further optimizations include, for example Figure 2 and Figure 4 As shown, in order to facilitate the control of the flow rate of the suction tube 200 or the flushing tube 300, the handle 110 is provided with a first control component 800 for controlling the flow rate of the suction tube 200 or the flushing tube 300. The first control component 800 can be a control plate, which is slidably disposed between the suction tube 200 and the flushing tube 300. Part of the control plate extends to the outside of the handle 110. Thus, in use, by sliding the control plate towards one side of the suction tube 200 or the flushing tube 300, the tube body is squeezed, and the cross-section of the internal channel of the tube body is reduced, thereby achieving the purpose of adjusting the flow rate.

[0038] Further optimizations include, for example Figure 2 and Figure 5 As shown, a second control component 900 is provided on the guide portion 120 for controlling the extension length of the suction tube 200 or the rinsing tube 300 beyond the end of the guide tube 130. In actual production and use, the second control component 900 can be provided on both the suction tube 200 and the rinsing tube 300. The second control component 900 is slidably disposed on the guide portion 120, and part of the second control component 900 is connected to the suction tube 200 and the rinsing tube 300. By controlling the second control component 900 to slide on the guide portion 120 (in the direction of approaching or moving away from the guide tube 130), the suction tube 200 or the rinsing tube 300 can be extended or retracted from the guide tube 130.

[0039] In summary, by inserting the suction tube 200 and the irrigation tube 300 into the tail of the handle 110, and the instrument tube 400 into the end of the guide portion 120 away from the guide tube 130, when the guide body 100 is held, the external device tubing connecting the suction tube 200 and the irrigation tube 300 is located at the bottom of the palm, while the instrument tube 400 is located at the top of the palm. The two do not interfere with each other, making it more convenient for doctors to use.

[0040] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
