Description

Pharyngeal push type hemostatic instrument

Technical Field

The utility model relates to the field of medical care appliances, in particular to a pharyngeal push type hemostatic instrument.

Background

When a throat operation or a large bleeding after a throat operation (such as tonsil operation) is performed, a hemostatic cotton ball is often inserted into the oral cavity of a patient and pressed against a bleeding point to stop bleeding. However, in many cases, the bleeding point is located in the pharynx of the patient, and since no hemostatic instrument specially used for the pharyngeal bleeding opening is available, medical staff often directly clamps a sterilized cotton ball by using hemostatic forceps and presses the cotton ball at the bleeding opening of the pharynx. However, the volume of the rear part of the hemostatic forceps is relatively large, the length of the hemostatic forceps is limited, the cotton ball is often difficult to accurately send to the position of a bleeding hole, the foreign body sensation of a patient is serious, once the cotton ball falls off, the cotton ball is very likely to enter the body of the patient along with the subconscious swallowing action of the patient, subsequent operations are needed, and more pain and economic burden are brought to the patient.

There is therefore a need for a method or apparatus that addresses the above-mentioned problems.

The technical solution of the utility model is that: a pharyngeal push type hemostatic instrument is characterized in that: the device comprises a telescopic rod 1, the telescopic rod 1 consists of a sleeve body 2 and a rod body 3 which are movably sleeved with each other, a plurality of positioning holes 4 which are uniformly distributed along the length direction of the sleeve body 2 are arranged on the sleeve body 2, positioning block grooves 5 which are distributed along the radial direction are arranged on the rod body 3, positioning blocks 7 are movably connected in the positioning block grooves 5 through springs 6, the diameter of each positioning block 7 is matched with that of each positioning hole 4, the end parts of the positioning blocks 7 are spherical, and the end parts of the rod bodies 3 are provided with clamping mechanisms,

the clamping mechanism comprises a fixed clamping plate 8 fixed at the end part of the rod body 3, a sliding groove 9 is formed in the end part of the rod body 3, a movable clamping plate 10 matched with the fixed clamping plate 8 is connected in the sliding groove 9 in a sliding mode, sawtooth-shaped stripes 11 are arranged on the inner sides of the fixed clamping plate 8 and the movable clamping plate 10, the outer side of the movable clamping plate 10 is rotatably connected with the end part of an adjusting bolt 12, the adjusting bolt 12 is rotatably connected on the rod body 3, and the axes of the fixed clamping plate 8 and the movable clamping plate 10 are arc lines,

the apparatus still including pressing cotton ball 13, be connected with anti-drop rope 14 on pressing cotton ball 13, anti-drop rope 14's the other end is provided with go-between 15, the bottom of the cover body 2 rotates and supports has the axle 16 that tightens up through torsional spring control, tighten up on the axle 16 then be provided with go-between 15 assorted couple 17.

Compared with the prior art, the utility model, have following advantage:

this kind of structural style's pharyngeal push type hemostatic devices, its simple structure, design benefit, it is rationally distributed, it is difficult to find suitable hemostatic devices's actual problem when having the hemorrhage mouth to pharyngeal, designs a neotype push type hemostatic devices. Its whole length is adjustable, and presses the fixed of cotton ball very firm, even if the problem that the cotton ball drops has appeared, under the effect of the axle that tightens up of its afterbody, presses the cotton ball and also can draw out from patient's pharynx fast, and fundamentally prevents that the cotton ball from taking place by the condition of swallowing. And the hemostatic instrument has simple manufacturing process and low manufacturing cost, so the hemostatic instrument has multiple advantages, is particularly suitable for popularization and application in the field, and has very wide market prospect.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 3: a pharyngeal push type hemostatic instrument comprises a telescopic rod 1, wherein the telescopic rod 1 is composed of a sleeve body 2 and a rod body 3 which are movably sleeved with each other, a plurality of positioning holes 4 which are uniformly distributed along the length direction of the sleeve body 2 are arranged on the sleeve body 2, positioning block grooves 5 which are distributed along the radial direction are arranged on the rod body 3, positioning blocks 7 are movably connected in the positioning block grooves 5 through springs 6, the diameter of each positioning block 7 is matched with that of each positioning hole 4, the end parts of the positioning blocks 7 are spherical, the end parts of the rod bodies 3 are provided with clamping mechanisms,

The utility model discloses pharyngeal push type hemostatic device's working process as follows: firstly, the whole length of the telescopic rod 1 is adjusted according to the specific position of a bleeding hole, the positioning block 7 can be clamped in a certain positioning hole 4 under the action of the spring 6, so that the whole length of the telescopic rod 1 is fixed, when the adjustment is needed, an operator only needs to press the positioning block 7, after the spherical end part of the positioning block 7 is recovered, the rod body 3 and the sleeve body 2 can be driven to move relatively, after the relative position of the rod body and the sleeve body is adjusted, the positioning block 7 is clamped in a certain positioning hole 4 again under the action of the spring 6, and the length of the telescopic rod 1 is fixed;

after the telescopic rod 1 is adjusted, a sterilized pressing cotton ball 13 is taken, the connecting ring 15 on the anti-falling rope 14 is hung on the hook 17, then the pressing cotton ball 13 is clamped by the clamping mechanism, and the anti-falling rope 14 is in a tightened state under the action of the tightening shaft 16 after the pressing cotton ball 13 is clamped as the tightening shaft 16 is controlled by the torsion spring (the tightening shaft 16 is properly rotated for several circles before the connecting ring 15 is hung on the hook 17);

the working process of the clamping mechanism is as follows: a pressing cotton ball 13 is placed between the fixed clamping plate 8 and the movable clamping plate 10, then the adjusting bolt 12 is rotated, the adjusting bolt 12 drives the movable clamping plate 10 to slide in the sliding groove 9 until the pressing cotton ball 13 is clamped by the two clamping plates;

after the preparation work is finished, an operator can hold the telescopic rod 1, the pressing cotton ball 13 is used for pressing the bleeding opening of the pharyngeal portion of the patient, and the axes of the fixed clamping plate 8 and the movable clamping plate 10 are both arc lines, so that the pressing is convenient, and the bleeding position can be accurately and stably pressed;

on one hand, under the effect of adjusting bolt 12, remove grip block 10 and have a self-locking function, and the jagged stripe 11 that increases frictional force still exists between two grip blocks, consequently can firmly the centre gripping press cotton ball 13 and prevent it from droing, even if press cotton ball 13 and take place to drop, tighten up axle 16 and can autogiration under the effect of torsional spring, tighten up anti-drop rope 14, and then will press cotton ball 13 and draw the afterbody of this device (on the axle 16 that tightens up promptly), can prevent fundamentally like this that to press cotton ball 13 from being swallowed by the patient.
