Description

Technical Field

[0001] The utility model belongs to the field of medical equipment and relates to a handle and a navigation trolley. Background Art

[0002] In medical surgery scenarios, navigation trolleys are widely used to assist doctors in positioning work. Navigation trolleys usually include a multi-axis connecting rod, at the end of which are small instruments and equipment such as cameras and light sources. In the above scenarios, users may need to frequently adjust the position of the camera so that the camera can maintain a good visual effect at all times, and the adjustment method is usually that the user directly pulls the camera with his hands. In this way, the user's hands will directly contact the camera, and it is easy for foreign matter to be stuck in front of the camera lens, affecting the image clarity. On the other hand, these small instruments and the front end of the movable connecting rod are usually detachable. Different small instruments will be disassembled and replaced for use in different usage scenarios. Therefore, the connection between the small instrument and the front end of the movable connecting rod is not a high-strength connection. When the user directly pulls the small instrument, multi-directional external forces will be generated on the connection part, which will cause deformation and loosening between the connection structures over time, and eventually cause the small instrument to loosen after it is installed.

[0018] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0019] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0020] All directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, horizontal, vertical...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0021] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present invention may actually be an approximately parallel relationship, and the vertical relationship may actually be an approximately vertical relationship.

[0022] This embodiment discloses a handle and a navigation trolley using the handle, referring to Figure 1 The navigation trolley includes a base 4 and a movable link 3, wherein the movable link 3 includes two ends, namely a front end 31 and a rear end 32, wherein the rear end 32 is connected to the base 4 for supporting the entire movable link 3, and the front end 31 is connected with a small instrument. A plurality of axes or joints are arranged between the front end 31 and the rear end 32 of the movable link 3, so that the movable link 3 can form a variety of postures through multi-angle adjustment of the joint, so as to form a stable support for the small instrument at the front end 31 while providing a spatial position adjustment function.

[0023] The navigation trolley in this embodiment can be used in medical surgery scenarios, and the small instrument can be a camera device.

[0024] In the above scenario, the user may need to frequently adjust the position of the camera so that the camera can maintain a good visual effect at all times, and the adjustment method is usually that the user directly pulls the camera with his hands. In this way, the user's hands will directly contact the camera, and it is easy for foreign matter to be contaminated in front of the camera lens, affecting the image clarity; on the other hand, these small instruments and the front end 31 of the movable connecting rod 3 are usually detachable, and different small instruments will be disassembled and replaced for use in different usage scenarios. Therefore, the connection between the small instrument and the front end 31 of the movable connecting rod 3 is not a high-strength connection. When the user directly pulls the small instrument, multi-directional external forces will be generated on the connection part, which will cause deformation and loosening between the connection structures over time, and finally cause the small instrument to loosen after being installed.

[0025] Furthermore, in this embodiment, the handle is additionally provided to provide the user with a traction portion 1, instead of directly traction of the small instrument; the handle can be arranged at the front end 31 of the movable connecting rod 3, and can also be arranged on the small instrument. In this embodiment, it is preferred that the handle is arranged on the small instrument because a joint is further provided between the small instrument and the front end 31 of the movable connecting rod 3, and thus the handle arranged on the small instrument can also drive the rotation adjustment of the small instrument relative to the front end 31 of the movable connecting rod 3.

[0026] Specifically, refer to Figure 2 , 3 4. A mounting seat 21 is provided on the small instrument, and the small instrument is fixedly connected to the mounting seat 21 in a detachable manner, so that the current small instrument can be removed and replaced with other small instruments; the mounting seat 21 is hinged to the front end 31 of the movable connecting rod 3, that is, a rotating shaft or joint is provided between the mounting seat 21 and the front end 31 of the movable connecting rod 3.

[0027] The handle is connected to the mounting base 21 instead of the small instrument, so when the handle is pulled, the applied traction acts on the mounting base 21 instead of the small instrument, thereby ensuring the stability of the detachable connection structure between the small instrument and the mounting base 21.

[0028] The handle includes a connecting portion 11 and a traction portion 1, and the handle includes two ends, one end of which is fixedly connected to the mounting seat 21, and the other end is fixedly connected to the traction portion 1. A gripping surface for contacting with a human hand to enable the human hand to grasp is formed on the traction portion 1, wherein the gripping surface at least contacts and abuts against the palm surface.

[0029] The traction part 1 includes but is not limited to a straight rod structure, a bent rod structure, an angled rod structure, etc. The rod surface forms the gripping surface. In the present embodiment, the traction part 1 is preferably an annular structure, so that the inner and outer circumferential surfaces of the annular structure both form gripping surfaces. When the user grasps it with his hand, part of the gripping surface can be in contact with the palm surface in the front, back, left, right, up and down directions, which is convenient for the user to apply traction more fully and provide a better user experience.

[0030] Furthermore, the traction portion 1 and the connection portion 11 are at a set angle, referring to Figure 3 As shown, the traction part 1 and the small instrument are oriented in roughly the same direction, thereby forming a spatial sensory experience for the user, so that the user does not need to always look at the small instrument during the traction action, and can clearly know the direction of the small instrument just by grasping it.

[0031] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
