Description

Technical Field

[0001] The utility model discloses an intracranial blood flow detection probe shaping tube and an adjusting device thereof, and relates to the technical field of intracranial blood flow monitoring probe auxiliary devices. Background Art

[0002] In neurosurgery, it is sometimes necessary to monitor the intracranial blood flow in real time. The current detection device used in clinical practice is an ultrasonic probe. In order to obtain a better blood flow image, the probe needs to be inserted into the surgical cavity. The specific device structure is referenced Figure 1 .

[0003] During the specific implementation process, the probe needs to be inserted into the surgical cavity using a clamping device such as pliers. Due to the small space and complex structure in the surgical cavity, the traditional placement method usually causes the probe to slip and become unable to be inserted. Currently, there is no probe placement auxiliary device that can solve the above problems.

[0004] In summary, the defects of the prior art are:

[0005] 1. The clamping device of the probe is prone to slipping during the insertion adjustment process.

[0006] 2. Since the probe is a simple soft tube structure, it cannot adapt to different spatial structures during the actual penetration process, and there is a problem that its own structure cannot be adjusted to adapt to different penetration spaces. Utility Model Content

[0007] The utility model aims to provide a shaping tube of an intracranial blood flow detection probe and an adjusting device thereof, so as to solve the problem that the current intracranial monitoring probe lacks a probing auxiliary device.

[0008] In order to achieve the above technical purpose and the above technical effect, the utility model is realized by the following technical solutions:

[0009] A shaping tube of an intracranial blood flow detection probe and an adjustment device thereof, comprising: a shaping sleeve, a shaping tube, the shaping tube being a clamping structure with a straight tube at the end, the shaping tube comprising a clamping portion and an adjustment portion, one end of the clamping portion being connected to two semicircular arc structures with the same diameter, and the other end being connected to the clamping structure, the clamping structure being an X-shaped shearing structure fixed by a rotating shaft, the rotating shaft being fixedly connected to the straight tube, the straight tube being provided with the adjustment portion, the adjustment portion comprising a through groove structure arranged on the wall of the straight tube and parallel to the axial direction of the straight tube, and a strip rod body matching the through groove structure, the end of the strip rod body being rotatably connected to a roller, and an outer surface of the straight tube structure being provided with an oblique groove.

[0010] Furthermore, the strip rod body and the through slot are both of a Chinese-shaped structure, small rods extend from both sides of the roller and are rotatably connected to the narrow variable of the strip rod body, and the strip rod body is 5-10 cm longer than the straight tube structure.

[0011] Furthermore, the inclined groove is arranged at a position corresponding to the through groove outside the straight tube, and the inclined groove is arranged at the end of the straight tube structure. The inclined groove is a right-angled triangle structure as a whole, and the width gradually decreases along the straight tube direction.

[0012] Furthermore, the number of the through slots, the inclined slots, the rollers, and the strip-shaped rod bodies are all 2 and are symmetrically distributed, and an elastic element is provided between the rollers and the strip-shaped rod bodies.

[0013] Beneficial effects:

[0014] The semicircular arc structure of the utility model can form a complete ring after being clamped. When the user operates the clamping component, the probe can be effectively clamped, thereby preventing the probe from slipping when being clamped.

[0015] The shaping sleeve described in the utility model is subjected to two-point forces under the action of the roller of the shaping tube and the clamping action of the semicircular arc structure. When the roller is offset, the shaping sleeve bends. The user can adjust the structure of the shaping tube according to the specific situation to adapt to different spatial structures.

[0021] In order to more clearly illustrate the technical solution of the embodiment of the utility model, the utility model will be described in detail with reference to the accompanying drawings.

[0022] Example

[0023] An intracranial blood flow detection probe shaping tube and its adjustment device described in this embodiment include: a shaping sleeve and a shaping tube.

[0024] It should be understood that in order to solve the problem that the probe cannot adapt to different spatial structures during the actual penetration process and its own structure cannot be adjusted, the shaping sleeve described in this embodiment needs to wrap the probe and select a plastic material structure, such as a thin metal material.

[0025] The shaping tube is a clamping structure with a straight tube at the end. The shaping tube includes a clamping part and an adjustment part. One end of the clamping part is connected with two semi-circular arc-shaped structures with the same diameter, and the other end is connected with the clamping structure. The clamping structure is an X-shaped shearing structure fixed by a rotating shaft.

[0026] In this embodiment, the X-shaped shearing structure of the clamping structure is a scissor handle structure, that is, the user can drive the semi-circular arc-shaped structure to achieve the clamping function by clamping the clamping structure.

[0027] The rotating shaft is fixedly connected to the straight tube. The straight tube is provided with the adjustment part. The adjustment part includes a through groove structure arranged on the straight tube wall and parallel to the axial direction of the straight tube and a strip-shaped rod body matching the through groove structure. The end of the strip-shaped rod body is rotatably connected with a roller, and the outer surface of the straight tube structure is provided with an inclined groove.

[0028] Both the strip-shaped rod body and the through groove are in the shape of the Chinese character 'zhong'. Small rods extend from both sides of the roller and are rotatably connected to the narrow part of the strip-shaped rod body. The strip-shaped rod body is 5 - 10 cm longer than the straight tube structure.

[0029] In this embodiment, the strip-shaped rod body selects a model that is 5 cm longer than the straight tube structure, and the height of the roller is flush with the highest position of the inclined groove.

[0030] The inclined groove is arranged at the position corresponding to the through groove on the outer side of the straight tube, and the inclined groove is arranged at the end of the straight tube structure. The whole inclined groove is a right triangle structure, and the width gradually decreases along the direction of the straight tube.

[0031] The number of the through groove, the inclined groove, the roller, and the strip-shaped rod body is 2 and they are symmetrically distributed. An elastic element is arranged between the roller and the strip-shaped rod body.

[0032] In this embodiment, the elastic element selects a spring, and the spring is parallel to the axial direction of the connection part.

[0033] It should be understood that the clamping structure operates the handle structure to clamp during operation, thereby driving the semicircular arc structure to clamp. In this embodiment, the semicircular arc structure is used to clamp the probe. When in use, the probe is inserted from one end of the straight tube and removed from the other end. At this time, the probe passes through the semicircular arc structure. Therefore, the probe is fixed when the semicircular arc structure is clamped and is released when the semicircular arc structure is released.

[0034] When the probe is clamped, the user pushes the strip rod to move, and the roller is offset to the side close to the axial direction of the straight cylinder under the limiting effect of the inclined groove. It should be understood that under the action of the connection of the elastic element, the roller can realize the offset function. After realizing the offset function, the roller will press the shaping sleeve to deform. It is not difficult to understand that during operation, the shaping sleeve can be reshaped to adapt to the complex spatial structure in the surgical cavity.

[0035] The above is only part of the embodiment of the application, and does not limit the application in any form. Any simple modification, equivalent changes and modifications made to the above embodiments still fall within the scope of protection of the technical solution of the application.
