Embodiment 1

[0033] as attached figure 1 , a microsurgery finger holder for hand surgery, the finger holder includes a substrate 210 and a plurality of support columns 220; the first surface of the substrate 210 is a working surface 211, including a plurality of through holes with sliding damping; The support column 220 is installed in cooperation with the through hole, and slides axially in the through hole along the central axis of the support column 220 and the through hole; a plurality of the support columns 220 are closely arranged and evenly covered The working surface 211 of the base plate 210; a plurality of the support columns 220 are used to support the patient's fingers and the bottom of the palm in the microsurgery, so that the relative positions of the patient's fingers and the palm are fixed; the finger holder also includes at least one Magnetic fixed handle 230; the fixed handle 230 is used in conjunction with the support column 220 to buckle and press the necessary fixed po...

Embodiment 2

[0055] This embodiment should be understood as at least including all the features of any one of the foregoing embodiments, and further improvements on the basis thereof;

[0056] In some usage situations, in addition to the vertical pressure on the support column, the patient's fingers or palms also have a certain squeezing force on the side of the support column, causing lateral deformation of the support column; Since it is necessary to ensure that the support end has a certain degree of flexibility, and at the same time, the support column needs to maintain a certain rigidity during the period of fixing the patient's finger or palm, the internal structure of the support column 220 is further improved in this embodiment;

[0057] Carry out multi-area division inside described support cushion 221, and make each area seal separately and independently; Figure 5 , the inside of the support cushion 221 is divided into 4 areas by a plurality of partitions 401, including a first ...

Embodiment 3

[0069] This embodiment should be understood as at least including all the features of any one of the foregoing embodiments, and further improvements on the basis thereof;

[0070] In this embodiment, the fixer includes one or more fixation handles 230; Image 6, the fixed handle 230 includes a first end 231 and a second end; the first end 231 includes a piece of magnetic material and is wrapped by an external protective shell; the first end and the second end are connected by a connecting band 232 connection; the material of the connecting belt 232 can be leather, doctor's silicone or fiber fabric, which is used to cover and fix the patient's fingers;

[0071] Further, as attached figure 2 As shown, on the top of the support end, an electromagnet 223 is embedded in the inner surface of the support cushion 221; the electromagnet 223 is connected to the power module through a power supply line, thereby generating a switchable magnetic force;

[0072] After the patient's finge...

Abstract

The invention relates to a finger fixator for hand surgery microsurgery. The finger fixator comprises a base plate and a plurality of supporting columns. The multiple supporting columns are tightly arranged and evenly cover the working face of the base plate. The supporting columns are used for supporting fingers and the bottom of a palm of a patient in a microsurgery, so that the relative positions of the fingers and the palm of the patient are fixed; the finger fixator further comprises at least one fixing handle, and the fixing handles are matched with the supporting columns and used for buckling and tightly pressing the fixing portions of the fingers and the palm of the patient. Wherein the bottom of the base plate and the supporting end of the supporting column are filled with an electrorheological fluid, when a finger or a palm of a patient is placed on the base plate, the supporting column and the supporting end are in a free moving state, and after the position of the finger or the palm of the patient is adjusted, working voltage is applied to the electrorheological fluid, and the electrorheological fluid acts on the supporting column. The base of the base plate and the supporting end are hardened, so that the fingers or the palm of the patient is fixed.

Description

technical field [0001] The present invention relates to the field of surgical instruments. In particular, it relates to a microsurgical finger holder for hand surgery. Background technique [0002] With the development of medical imaging technology, more and more surgical operations on tiny parts of the human body involve the use of high-definition imaging microscopes. Surgical microsurgery needs to use microscope equipment to accurately focus on the target part, so it is required that the observed target part has a sufficient degree of fixation to avoid defocusing during observation; at the same time, operations such as the hand involve many nerves , vascular distribution, it is necessary to maintain high fixation of the hand during the operation, so the fixation device of the fingers has been an important research topic in related research fields. [0003] Consult the relevant disclosed technical solutions. The technical solution with the publication number CN208626109 (...
