Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of special instrument vehicles, in particular to a special instrument vehicle for a neurosurgery navigation and positioning system. Background Art
[0002] The neurosurgery navigation and positioning system consists of a robotic arm (including GD-60A and GD-66A guides), surgical navigation software (RemebotSGS, released version V3.0), an optical tracking locator, a special instrument cart, positioning landmarks (RM-08A, MK-06A, MK-1IA), and a probe. The surgical navigation software reads the CT / MRI images of the patient's preoperative scan and creates a three-dimensional model of the brain. The doctor sets the surgical target and path based on his or her own experience and judgment. The optical tracking locator automatically visually recognizes the characteristic landmark blocks and quickly completes the robotic arm registration and patient registration, thereby establishing the conversion relationship between the image space and the robotic arm space. The robotic arm realizes accurate automatic positioning and navigation of the planned target and path based on the registration conversion results, and locks the joints after being in place, and loads the surgical instruments to support the surgical operation. Among them, the robotic arm registration establishes the conversion relationship between the robotic arm space and the optical tracking locator space, and the patient registration establishes the conversion relationship between the image space and the optical tracking locator space. It can be applied to children over 4 years old and recognized neurological cases to spatially locate and orient surgical instruments.
[0003] The dedicated instrument cart in the existing neurosurgery navigation and positioning system is mainly used to carry robotic arms, display screens and some surgical instruments for easy movement and transportation. However, the existing dedicated instrument cart mainly relies on universal wheel movement and the wheel brakes on the universal wheels to position and fix the instrument cart. The wheel brake fixing effect is average, and the instrument cart is still prone to slight shaking, which affects the stability of the placement of the dedicated cart during use and reduces its use effect.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] The utility model provides Figures 1-4 A special instrument cart for a neurosurgery navigation and positioning system shown in the figure comprises an instrument cart body 101 and a movable universal wheel 105 installed at the bottom of the instrument cart body 101. The movable universal wheel 105 can drive the instrument cart body 101 to move and transport, so as to facilitate use in multiple places. A support foot 201 is provided at the bottom of the instrument cart body 101 and between two adjacent movable universal wheels 105. A lifting mechanism is provided inside the instrument cart body 101. The telescopic end of the lifting mechanism extends to the bottom of the instrument cart body 101 and is fixedly connected with a connecting plate 204 for connecting multiple supporting feet 201. The lifting mechanism drives the connecting plate 204 to move downward, so that the multiple supporting feet 201 touch the ground and prop up the instrument cart body 101 off the ground, thereby being able to keep the instrument cart body 101 firmly placed and maintain its stability during use.
[0021] A damper 202 is fixedly provided between the bottom end of the connecting plate 204 and the supporting foot 201, and a shock-absorbing spring 203 is sleeved on the outside of the damper 202. The damper 202 cooperates with the shock-absorbing spring 203 to achieve a shock-absorbing effect on the instrument vehicle body 101 when the supporting foot 201 touches the ground, thereby further improving the stability of the instrument vehicle body 101 during use.
[0022] In a preferred embodiment, a fixing block 302 is fixedly provided in the middle of the bottom end of the connecting plate 204, and two reinforcing ribs 301 are symmetrically fixedly connected to the four side walls of the fixing block 302. The reinforcing ribs 301 extend to the end position of the connecting plate 204 at one end away from the fixing block 302. The fixing block 302 is in the shape of a right-angled triangle. The fixing block 302 cooperates with the reinforcing ribs 301 in the shape of a right-angled triangle, which can reinforce the connecting plate 204, thereby improving the rigidity of the connecting plate 204 and preventing it from being damaged easily, thereby providing a stable supporting force for the supporting foot 201.
[0023] Among them, the jacking mechanism includes a hydraulic telescopic rod 206 fixedly installed inside the instrument vehicle body 101, which is used to drive the connection plate 204 to rise and fall.

Through the lifting switch, the user can conveniently control the extension or shortening of the hydraulic telescopic rod 206, thereby increasing the convenience of operation.
[0025] In a preferred embodiment, the supporting foot 201 includes a bottom foot 211 and a top foot 212. An internally threaded sleeve 213 is fixedly provided on the side of the bottom foot 211 opposite to the top foot 212, and an externally threaded rod 214 is fixedly provided on the side of the top foot 212 opposite to the bottom foot 211. A rubber pad 215 is fixedly provided on the side of the bottom foot 211 away from the top foot 212, and a mounting groove 216 is provided on the side of the top foot 212 away from the bottom foot 211 for mounting and positioning the damper 202. The bottom foot 211 and the top foot 212 are fixed by a threaded connection between the internally threaded sleeve 213 and the externally threaded rod 214, so that the supporting foot 201 can be set as a detachable structure for easy maintenance. At the same time, the rubber pad 215 can have the effect of silencing and buffering, thereby improving the supporting effect on the instrument vehicle body 101.
