AI Technical Summary

Benefits of technology

The system streamlines surgical procedures by enabling efficient penetration and manipulation of instruments through both soft and hard tissues, reducing the complexity and time required for accessing interior body regions.

Problems solved by technology

The common need to use different instruments in a given procedure, coupled with the absolute need to accurately and reliably deploy each of these different instruments through both soft and hard tissue, often with an enhanced mechanical advantage, complicate the physician's already difficult task.
The need to handle different instruments in different ways for different purposes can distract the physician and lead to wasted effort, which lengthen the overall time of the procedure.

Embodiment Construction

[0045]FIG. 1 shows a system 10 for penetrating tissue. The system includes one or more functional instruments 12, 14, and 16 and a handle 18. The handle 18 engages at least one of the functional instruments 12, 14, and 16 in a removable, slip fit fashion to aid a physician in manipulating the instrument 12, 14, or 16 during use.

I. The Instruments

[0046] The number and type of instruments 12, 14, and 16 can vary. FIG. 1 shows three representative instruments 12, 14, and 16, each having a different size and function.

[0047] The first, second, and third instruments 12, 14, and 16 share some common features, although they are intended, in use, to perform different functions. The first, second and third instrument 12, 14, and 16 each comprises an elongated, cylindrical body 20 having a proximal end 22 and a distal end 24. The first, second, and third instrument 12, 14, and 16 are each made of a rigid, surgical grade plastic or metal material.

Abstract

A cannula instrument is deployed in soft tissue to form a percutaneous access path to bone. A guide pin instrument is sized and configured for passage through a bore of the cannula instrument. A handle separate from the cannula instrument and the guide pin instrument includes an attachment component configured to selectively engage or disengage the handle attachment site of the cannula instrument to aid in advancement of the cannula instrument through soft tissue and form the percutaneous access path. A passageway in the handle accommodates passage of the guide pin instrument through the handle to accommodate sliding the handle over and relative to the guide pin instrument when selectively engaging or disengaging the attachment component and the handle attachment site. A therapeutic instrument is deployed through the percutaneous access path.

Description

RELATED APPLICATIONS [0001] This application is a divisional of co-pending application Ser. No. 10 / 227,714, filed Aug. 26, 2002, which is a divisional of application Ser. No. 09 / 014,229, filed Jan. 27, 1998, now U.S. Pat. No. 6,468,279.FIELD OF THE INVENTION [0002] The invention generally relates to hand-held surgical instruments and to procedures that deploy these instruments through tissue to access interior regions of the body. BACKGROUND OF THE INVENTION [0003] There are many different types and styles of hand-held surgical instruments that physicians use to gain access into interior body regions. These instruments are intended to penetrate tissue by the application of pushing forces, twisting forces, or both in combination. [0004] Often, a single surgical procedure will require the physician to employ different surgical instruments, each possessing a different shape, size, and function. Often, the procedure will require the physician to deploy these instruments in both soft and...
