Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a neurosurgical stereotactic positioning frame shielding device. Background Technology

[0002] In clinical surgeries requiring craniotomy for localization, stereotactic positioning devices are commonly used. These devices consist of a positioning frame and at least four vertical positioning arms with through-holes. Medical personnel use this device to locate the surgical area by fixing it to the patient's head. Since the instruments used for localization need to penetrate the patient's skin tissue, the puncture site is susceptible to bacterial contamination if continuously exposed. Currently, the primary clinical practice is to wrap the patient's head with a medical drape to prevent infection at the puncture site. However, the drape may detach during patient movement, thus failing to provide adequate protection, and the cost of using a medical drape is relatively high. Furthermore, wrapping the head with a medical drape can cause psychological resistance in patients, negatively impacting their experience.

[0003] Therefore, a shielding device is designed to prevent wound infection and protect patient privacy without affecting normal treatment. Specifically, this shielding device is a neurosurgical stereotactic frame shielding device. Utility Model Content

[0004] To overcome the problems mentioned in the background art, the present invention adopts the following technical solution:

[0005] A neurosurgical stereotactic positioning frame shielding device includes a cap body with a receiving channel inside the cap body. The receiving channel includes a distal end that directly communicates with the outside and a proximal end located inside the cap body. An operating channel is provided through the cap body, communicating with the proximal end of the receiving channel. A shielding member is connected to the cap body, and the shielding member can connect to the operating channel. When the shielding member is connected to the operating channel, the operating channel is not connected to the outside. The receiving channel is used for the four positioning arms of the puncture positioning frame to pass through. After the positioning arms extend into the receiving channel, they eventually reach the proximal end of the receiving channel. When the positioning arms reach the proximal end of the receiving channel, the operating channel aligns with the through holes on the positioning arms, thereby protecting patient privacy while ensuring the normal use of the puncture positioning frame. The shielding member can block the operating channel when not in a treatment state.

[0006] Furthermore, the cap has an outer wall and an inner wall, the outer wall and the inner wall being opposite to each other. When in use, the outer wall is away from the patient's head and the inner wall faces the patient's head. The operating channel includes an outer section that extends from the outer wall into the receiving channel and an inner section that extends from the inner wall into the receiving channel. When the shielding member is connected to the operating channel, the thickness of the portion entering the operating channel is not greater than the axial length of the outer section.

[0007] Furthermore, the shielding component includes a baffle and a strap, the baffle and the strap are connected, the strap is connected to the cap body, the strap is flexible, and the strap deforms under the action of the baffle when the baffle moves; the baffle can be connected to the operating channel.

[0008] Furthermore, when the baffle is connected to the operating channel, a first fitting part is provided at the end opposite to the cap body, and a second fitting part is provided on the cap body. The baffle can detach from the operating channel and move to a fitting position. When the baffle is in the fitting position, the first fitting part is connected to the second fitting part.

[0009] Furthermore, the outer section of the operating channel is elastic, and the baffle is also elastic. The outer contour of the baffle is the same as the inner contour of the outer section, and the baffle can be embedded in the outer section and block the operating channel.

[0010] Furthermore, each of the receiving channels is connected to at least one of the operating channels, and a shielding member is provided outside each of the operating channels; the cap body is provided with at least four of the receiving channels, and the four receiving channels are arranged inside the cap body in a sagittal plane mirror image of the cap body.

[0011] Furthermore, the number of straps connecting each of the baffles is at least one.

[0012] Furthermore, both the first and second adhesive parts are either Velcro or magnetic, with the area of ​​the second adhesive part being larger than that of the first adhesive part. This allows for control of the fixed posture of the baffle by adjusting the connection position between the first and second adhesive parts.

[0013] Furthermore, the axial length of the inner segment is not less than the axial length of the outer segment.

[0014] Furthermore, the inner diameter of the inner segment is not less than the inner diameter of the outer segment.

[0015] The beneficial effects of this utility model are:

[0016] By setting a uniform cap, it can replace the currently used medical drape without causing psychological resistance from patients. By setting several receiving channels inside the cap, and each receiving channel is connected to at least one operating channel running through both the inside and outside of the cap, the cap can be assembled with the puncture positioning frame. At the same time, it does not affect medical personnel to insert the puncture instrument through the positioning arm into the patient's skull from the outside of the cap. In addition, a baffle is set up to cover the operating channel or move to a fitting position. The puncture point can be exposed or covered according to the actual treatment needs, thereby effectively protecting patient privacy and reducing the risk of infection at the puncture point.

Detailed Implementation

[0026] The technical solutions of this utility model are clearly and completely described below through specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] A neurosurgical stereotactic frame occlusion device, such as Figure 1-6As shown, the device includes: a cap body 1, with a receiving channel 11 inside the cap body 1. The receiving channel 11 includes a distal end 111 directly communicating with the outside, and a proximal end 112 located inside the cap body 1. An operating channel 12 is provided through the cap body 1, communicating with the proximal end 112 of the receiving channel 11. A shielding member 13 is connected to the cap body 1, and the shielding member 13 can be connected to the operating channel 12. When the shielding member 13 is connected to the operating channel 12, the operating channel 12 is not communicating with the outside. The receiving channel 11 is used for the four positioning arms of the puncture positioning frame to pass through. After the positioning arms extend into the receiving channel 11, they eventually reach the proximal end 112 of the receiving channel 11. When the positioning arms reach the proximal end 112 of the receiving channel 11, the operating channel 12 is aligned with the through holes on the positioning arms, thereby protecting patient privacy while ensuring the normal use of the puncture positioning frame. The shielding member 13 can block the operating channel 12 in the non-treatment state, thereby preventing external contaminants from entering the patient's wound and causing infection.

[0028] In some embodiments of this application, such as Figure 1-6 As shown, the cap body 1 has an outer wall 14 and an inner wall 15, with the outer wall 14 and the inner wall 15 facing away from each other. When in use, the outer wall 14 faces away from the patient's head and the inner wall 15 faces the patient's head. The operating channel 12 includes an outer section 121 that extends from the outer wall 14 into the receiving channel 11 and an inner section 122 that extends from the inner wall 15 into the receiving channel. When the shielding member 13 is connected to the operating channel 12, the thickness of the portion entering the operating channel 12 is not greater than the axial length of the outer section 121.

[0029] In some embodiments of this application, such as Figure 1-6 As shown, the shielding component 13 includes a baffle 131 and a strap 132. The baffle 131 is connected to the strap 132, and the strap 132 is connected to the cap body 1. The strap 132 is flexible. When the baffle 131 moves, the strap 132 deforms under the action of the baffle 131. The baffle 131 can be connected to the operating channel 12 to block the operating channel 12 in the non-treatment state. This helps to reduce the risk of infection for patients without affecting the treatment operation, while further strengthening the protection of patient privacy and reducing the psychological burden on patients.

[0030] In some embodiments of this application, such as Figure 1-6As shown, when the baffle 131 is connected to the operating channel 12, a first fitting part 1311 is provided at the end opposite to the cap body 1, and a second fitting part 1312 is provided on the cap body 1. The baffle 131 can detach from the operating channel 12 and move to a fitting position. When the baffle 131 is in the fitting position, the first fitting part 1311 and the second fitting part 1312 are connected. During puncture or intracranial treatment, the baffle 131 can be fixed to the cap body 1 through the connection of the first fitting part 1311 and the second fitting part 1312, thereby ensuring continuous communication between both sides of the operating channel 12. After the operation is completed, the baffle 131 can be manually reset, thereby blocking the operating channel 12 and covering the patient's wound.

[0031] In some embodiments of this application, such as Figure 1-6 As shown, the outer segment 121 of the operating channel 12 is elastic, and the baffle 131 is also elastic. The outer contour of the baffle 131 is the same as the inner contour of the outer segment 121, and the baffle 131 can be embedded in the outer segment 121 and block the operating channel 12. The number of straps 132 connecting each baffle 131 is at least one. Specifically, the baffle 131 has a protrusion on the side connected to the operating channel 12. The protrusion is columnar with the same cross-section along the direction perpendicular to the baffle 131, which allows the baffle 131 to be inserted into the operating channel 12 through the protrusion. The protrusion is made of sterile medical plastic or silicone, and therefore has a certain degree of elasticity; or, the baffle 131 has an elastic buckle on the side facing the cap 1. The elastic buckle can engage with the operating channel 12 when the baffle 131 abuts against the cap 1. When the baffle 131 is pulled by an external force, the elastic buckle deforms elastically and disengages from the operating channel 12.

[0032] In some embodiments of this application, such as Figure 1-6 As shown, each receiving channel 11 is connected to at least one operating channel 12, and a shielding member 13 is provided outside each operating channel 12; at least four receiving channels 11 are provided on the cap body 1, and the four receiving channels 11 are arranged inside the cap body 1 in a sagittal plane mirror image about the cap body 1, respectively for receiving different positioning arms of the positioning frame.

[0033] In some embodiments of this application, such as Figure 1-6 As shown, both the first adhesive part 1311 and the second adhesive part 1312 are either hook and loop fasteners or magnetic fasteners, and the area of ​​the second adhesive part 1312 is larger than that of the first adhesive part 1311. This allows for control of the fixed posture of the baffle 131 by adjusting the connection position between the first adhesive part 1311 and the second adhesive part 1312.

[0034] In some embodiments of this application, such as Figure 1-6As shown, the axial length of the inner section 122 is not less than the axial length of the outer section 121. The inner diameter of the inner section 122 is not less than the inner diameter of the outer section 121. After connection, since the outer section 121 is between the outer wall 14 and the receiving channel 11, the correspondence between the outer section 121 and the positioning hole of the positioning arm is easy to adjust. However, since the inner section 122 between the inner wall 15 and the operating channel 12 is located inside the cap body 1 close to the patient, the adjustment is relatively complicated. Therefore, by setting a larger inner diameter for the inner section 122, it is beneficial to prevent the inner section 122 from blocking the positioning hole on the positioning arm after the positioning frame and the cap body 1 are assembled.
