Abstract

The utility model discloses a kind of Multifunctional surgical drag hook, it comprises forearm and tail arm, and the front end of forearm is provided with rotating shaft, and forearm is fixed with hook portion through this rotating shaft; Be provided with some intermediate arms between forearm and tail arm, forearm, some intermediate arms and tail arm are connected through some three-dimensional movable joint respectively.Because this Multifunctional surgical drag hook is made up of more piece, and adopt three-dimensional movable joint to connect and compose, in use can regulate arbitrarily shape, the angle of surgery tractor as required, make it fully avoid the space needing in operation activity to utilize, thus make operation technique more convenient; Meanwhile, its hook portion have employed and in the past different articulated manner, after rotating, this device can be utilized to fix skin and tissue by the mode supported, further increase use motility and the suitability of this Multifunctional surgical drag hook thus.

Description

Multifunctional surgical drag hook

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly relates to the Multifunctional surgical drag hook of Clinical practice.

Background technology

Surgery tractor in clinical operation, for skin peptide or the tissue of tractive incision site, fully to expose visual area.Current surgery tractor is generally made up of hook portion and arm, both normally one, both angle and direction can not be regulated as required, in use there is many deficiencies.Also adjustable surgery tractor is had to occur at present, hook portion and arm normally adopt articulated manner to be connected by it, its regulative mode is confined in a plane usually, and angle adjustable is less, three-dimensional adjustment can not be carried out, can not expose visual area fully in operation process, it can cause certain obstruction to operation technique even sometimes.In addition, existing surgery tractor in use, is all the object realizing pining down skin and tissue with tractive, often limits by operative site, and makes drag hook inconvenience or can not firmly be fixed, and also brings some inconvenience to operation technique simultaneously.

Utility model content

For overcoming prior art problem, it is simple that this utility model provides a kind of structure, and easy to use, hook portion and arm can carry out three-dimensional regulation, can ensure that direction of draw is proper, the Multifunctional surgical drag hook of drag hook self to the obstacle that operation operating band is come can be reduced again.

For realizing above-mentioned technical purpose, this utility model by the following technical solutions: a kind of Multifunctional surgical drag hook, comprises forearm and tail arm, and the front end of forearm is provided with a perpendicular rotating shaft, and forearm is fixed with a curved hook portion through this rotating shaft; Tail arm is provided with handle, and is provided with retainer ring at tail end; Be provided with some intermediate arms between described forearm and tail arm, forearm, some intermediate arms and tail arm are connected through some three-dimensional movable joint respectively; Described three-dimensional movable joint is made up of ball and the spherical shell be placed on outside ball, both can relatively rotate, it is uncovered that spherical shell is provided with a circle little compared with ball diameter, and described ball is fixed with once uncovered outward extending first linking arm of circle, spherical shell is provided with the second linking arm; The second described linking arm and spherical shell are made up of two parts of symmetry, the retaining ring of above-mentioned two parts through being nested with outside the second linking arm and linking into an integrated entity, and the two-part interface of spherical shell is provided with some location structures; Described spherical shell is separately provided with a threaded engagement, for locking the bolt of ball and spherical shell relative position; The first above-mentioned linking arm, the second linking arm are respectively used to connect forearm, intermediate arm and tail arm.

This utility model has following beneficial effect: because this Multifunctional surgical drag hook is made up of more piece, and adopt three-dimensional movable joint to connect and compose, in use can regulate arbitrarily shape, the angle of surgery tractor as required, make it fully avoid the space needing in operation activity to utilize, thus make operation technique more convenient; Meanwhile, its hook portion have employed and in the past different articulated manner, after rotating, this device can be utilized to fix skin and tissue by the mode supported, further increase use motility and the suitability of this Multifunctional surgical drag hook thus.This Multifunctional surgical hook structure is simple, and implement easily, simple operation, can be used for all kinds of surgical operation, and then has practicality significantly.

Detailed description of the invention

Shown in Fig. 1,2, a kind of Multifunctional surgical drag hook disclosed in this utility model, comprise forearm 3 and tail arm 6, the front end of forearm 3 is provided with a perpendicular rotating shaft 2, and forearm 3 is fixed with a curved hook portion 1 through this rotating shaft 2; Tail arm 6 is provided with handle 7, and is provided with retainer ring 8 at tail end; Be provided with some intermediate arms 5 between described forearm 3 and tail arm 6, forearm 3, some intermediate arms 5 and tail arm 6 are connected through some three-dimensional movable joint 4 respectively; Described three-dimensional movable joint 4 is made up of ball 13 and the spherical shell 15 be placed on outside ball 13, both can relatively rotate, spherical shell 15 is provided with a circle uncovered 14 little compared with ball 13 diameter, described ball 13 is fixed with once uncovered 14 outward extending first linking arms 9 of circle, spherical shell 15 is provided with the second linking arm 10; The second described linking arm 10 and spherical shell 15 are made up of two parts of symmetry, the retaining ring 11 of above-mentioned two parts through being nested with outside the second linking arm 10 and linking into an integrated entity, and the two-part interface of spherical shell 15 is provided with some location structures 16; Described spherical shell 15 is separately provided with a threaded engagement, for locking the bolt 12 of ball 13 and spherical shell 15 relative position; The first above-mentioned linking arm 9, second linking arm 10 is respectively used to connect forearm 3, intermediate arm 5 and tail arm 6.

Because this Multifunctional surgical drag hook is made up of more piece, and adopt three-dimensional movable joint to connect and compose, in use can regulate arbitrarily shape, the angle of surgery tractor as required, make it fully avoid the space needing in operation activity to utilize, thus make operation technique more convenient; Meanwhile, its hook portion 1 have employed and connects mode from the past different dumplings, after rotating, this device can be utilized to fix skin and tissue by the mode supported, further increase use motility and the suitability of this Multifunctional surgical drag hook thus.
