Description

Winding and shaping tool

Technical Field

The utility model relates to the field of medical technology, in particular to coiling setting tool.

Background

The liquid inlet pipe is a core component of the cryoablation system, one end of the liquid inlet pipe is provided with a spray hole, and the liquid inlet pipe is mainly used for transporting liquid laughing gas in the device to the inside of the saccule and uniformly spraying the liquid laughing gas. Because the spiral plate is required to be fixed on the outer wall of the inner tube and the spray hole can not be shielded by the inner tube, the spiral plate is made on the inner tube to be the best scheme.

The liquid inlet pipe is made of nickel-titanium alloy (NiTi), and the raw material is a straight pipe, so that plastic deformation is not easy to generate at normal temperature, and the liquid inlet pipe needs to be coiled into a spiral shape by means of force application of a tool and is shaped.

The existing winding working modes mainly include two types:

the first method is as follows: for raw materials which are not easy to generate plastic deformation at normal temperature, the raw materials are generally wound and fixed firstly and then heated for destressing and shaping. During winding, one end is fixed, the free end applies a tension force to ensure that the liquid inlet pipe is attached to the driving part, and the force is required to be maintained all the time to overcome the restoring force of the liquid inlet pipe in the process.

The second method comprises the following steps: for raw materials which are easy to generate plastic deformation at normal temperature or the situation that the plasticity of the raw materials is enhanced by heating in advance, a constant positive pressure is generally applied to a bending part to enable a winding object to be directly subjected to plastic bending, and the force is not required to be maintained in the subsequent process.

The two working methods have the following defects:

in the first way, as mentioned above, in order to deform the material and prevent it from returning, the free end requires a great tension, in the same direction as the axis, which causes two problems: firstly, excessive positive pressure is generated on materials: in order to generate the tension, strong positive pressure needs to be applied to the free end and the fixed end of the material by external force, the material can be damaged by the excessive positive pressure, and the force value needs to be controlled under the condition that one end of the pipe needs to be kept; secondly, an overlarge positive pressure is generated on the driving part: the tension behind the loop acts primarily on the drive, which can buckle or snap if the force is excessive.

For the second mode, for some materials which are not easy to generate plastic deformation at normal temperature or occasions which are not suitable for being subjected to pre-heat treatment, the second mode has limited effect or is difficult to implement. The prior heat treatment can deform the section of the pipe when bending and applying force, and the mode is not suitable for winding the thin-wall pipe.

In addition, the first method has the following problems:

(1) the existing tooling equipment can generate indentation on the surface of a pipe during winding, so that the liquid inlet flow is influenced by a light person, the liquid inlet pipe is brittle and broken by a heavy person, and the pipe is scrapped;

(2) the finished product size is greatly influenced by human factors when being wound by the existing tool equipment, and the finished product size is different in the same batch, so that the service performance is finally influenced;

(3) the existing winding method has requirements on the holding power of operators due to the structure of a tool, the labor intensity is large, and partial operation may cause physical damage to operators;

generally, the existing tooling equipment is not high in yield and is not friendly to operators, and needs to be improved urgently.

The arrangement of the screwing slope 15 and the bending slope 10 facilitates the wire winding 3 to penetrate out of the guide opening 16, and meanwhile, the damage to the outer wall of the wire winding 3 can be prevented. Wherein, the bending slope 10 is closer to the other side wall of the V-shaped notch than the screwing slope 15.

In this embodiment, preferably, when the driving portion 5 rotates with itself for one turn, the distance of the driving portion moving along the axial direction of the limiting portion 4 is equal to the diameter of the winding wire 3, where the diameter of the winding wire 3 is the diameter of the winding wire itself when the winding wire is not wound. In this way, when the wire winding is performed, as shown in fig. 5, the screwed-in wire winding 3 just fills the internal space surrounded by the hole walls of the first screw platform 23, the second screw platform 32, the driving part 5, and the limiting part 4, and both ends of the wire winding spiral section 31 are limited by the first screw platform 23 and the second screw platform 32, so that the wire winding 3 is ensured not to be reset.

That is, in the winding and shaping tool provided in this embodiment, the thread pitch of the feeding thread section 20 of the driving portion 5 is the same as the diameter of the winding wire 3, so that the winding wire 3 wound around the driving portion 5 by the rotational screwing of the driving portion 5 is sufficiently axially and radially limited in the inner space, and thus, the deformation caused by the loosening of the winding wire 3 during the winding process can be avoided.

As shown in fig. 2, the driving portion 5 further includes a head section that is closer to the guide portion 2 than the feeding screw section 20, the head section includes an outer shaft 22 and an inner shaft 17 that extends out of the outer shaft 22 from an end of the outer shaft 22 that is away from the feeding screw section 20, the inner shaft 17 extends out of the stopper portion 4 after the driving portion 5 has been inserted into the stopper portion 4, the inner shaft 17 is inserted into the guide portion 2 after the guide portion 2 and the stopper portion 4 are relatively fixed, the guide portion 2 has an inner shaft guide hole 12 that is provided in an axial direction, an aperture of the inner shaft guide hole 12 matches an outer diameter of the inner shaft 17, and the second screw step 32 is provided around the inner shaft guide hole 12.

As shown in fig. 6, the stopper portion 4 has a guide hole 25 (hereinafter, referred to as an outer shaft guide hole 25), and the outer shaft guide hole 25 has an inner diameter matched with the outer diameter of the outer shaft 22 and smaller than the inner diameter of the feed screw hole 27. With this configuration, when the driving portion 5 is inserted into the limiting portion 4, the feeding screw thread section 20 can only reach the end surface of the feeding screw hole 27 that is connected to the outer shaft guide hole 25, that is, the end surface constitutes the limiting surface 26 of the feeding screw thread section 20, and the driving portion 5 can be screwed into the deepest position in the limiting portion 4.

After the driving portion 5 is disposed through the limiting portion 4, the outer shaft 22 extends out of the limiting portion 4 or the outer shaft 22 is close to the end face of the guiding portion 2 and the end face of the limiting portion 4 close to the guiding portion 2 are flush.

Particularly, after the driving portion 5 is inserted into the limiting portion 4, the tail section 21 may be located at one end of the limiting portion 4 far away from the guiding portion 2, and the tail section 21 may be a square head section to better transmit external torque.

In this embodiment, the driving portion 5 has a wire groove 19 formed in a side wall thereof and distributed in an axial direction, and specifically, the wire groove 19 is formed in sequence along the tail section 21, the feeding screw section 20, and the outer shaft 22.

In an embodiment, specifically, as shown in fig. 2, a bottom of one side wall of the wire groove 19 may be chamfered at an end of the outer shaft 22 away from the feeding screw section 20, so that a bottom surface of the side wall is tangential to a surface of the inner shaft 17, and a bending slope 18 of the driving portion is formed at an end of the outer shaft 22 away from the feeding screw section 20, thereby achieving a smooth transition.

After first spiral platform 23 with second spiral platform 32 is supporting to be arranged, the slope 10 of buckling of guide portion with the slope 18 of buckling of drive division forms spacing space, and when the wire winding 3 stretched into, the slope of the slope 10 of buckling of guide portion with the spacing space of the slope 18 of buckling of drive division slope 18's slope formation carries out preliminary bending and fixes wire winding 3, prevents wire winding 3 back-and-forth movement in wire casing 19, provides a smooth transition's region for wire winding 3 simultaneously, prevents that wire winding 3 surface is impaired or brittle fracture.

In this embodiment, as shown in fig. 1, the winding and shaping tool further includes a pressing mechanism, and the pressing mechanism is configured to detachably fix the guiding portion 2 to the limiting portion 4.

Preferably, the set angle may be defined as an angle between the guide surface 161 and the line groove 19, and the set angle ranges from-10 ° to 35 °. It should be noted that when the set angle is a negative value, the line groove 19 is located in the clockwise direction of the guide surface 161, when the set angle is a positive value, the line groove 19 is located in the counterclockwise direction of the guide surface 161, and as shown in fig. 9, the angle of the guide surface 161 with respect to the line groove 19 is α °, that is, the set angle is α °. .
